A Sketch of the Phonology and Grammar of Rajbanshi

This dissertation is a synchronic description of the phonology and grammar of two dialects of the Rajbanshi language (Eastern Indo-Aryan) as spoken in Jhapa, Nepal. I have primarily confined the analysis to the oral expression, since the emerging literary form is still in its infancy. The grammatical analysis is therefore based, for the most part, on a corpus of oral narrative text which was recorded and transcribed from three informants from north-east Jhapa. An informant, speaking a dialect from south-west Jhapa cross checked this text corpus and provided additional elicited material. I have described the phonology, morphology and syntax of the language, and also one aspect of its discourse structure. For the most part the phonology follows the basic Indo-Aryan pattern. Derivational morphology, compounding, reduplication, echo formation and onomatopoeic constructions are considered, as well as number, noun classes (their assignment and grammatical function), pronouns, and case and postpositions. In verbal morphology I cover causative stems, the copula, primary and secondary agreement, tense, aspect, mood, auxiliary constructions and non-finite forms. The term secondary agreement here refers to genitive agreement, dative-subject agreement and patient (and sometimes patient-agent) agreement. The breaking of default agreement rules has a range of pragmatic inferences. I argue that a distinction, based on formal, semantic and statistical grounds, should be made between conjunct verbs, derivational compound verbs and quasi-aspectual compound verbs. Rajbanshi has an open set of adjectives, and it additionally makes use of a restricted set of nouns which can function as adjectives. Various particles, and the emphatic and conjunctive clitics are also considered. The syntactic structures studied include: non-declarative speech acts, phrase-internal and clause-internal constituent order, negation, subordination, coordination and valence adjustment. I explain how the future, present and past tenses in Rajbanshi oral narratives do not seem to maintain a time reference, but rather to indicate a distinction between background and foreground information. I call this tense neutralisation .

Suomen rautakautiset kulkuset, kellot ja kelloriipukset : äänimaiseman arkeologiaa

The thesis addresses the problem of Finnish Iron Age bells, pellet bells and bell pendants, previously unexplored musical artefacts from 400–1300 AD. The study, which contributes to the field of music archaeology, aims to provide a gateway to ancient soundworlds and ideas of music making. The research questions include: Where did these metal artefacts come from? How did they sound? How were they used? What did their sound mean to the people of the Iron Age? The data collected at the National Museum of Finland and at several provincial museums covers a total of 486 bells, pellet bells and bell pendants. By means of a cluster analysis, each category was divided into several subgroups. The subgroups, which all seem to have a different dating and geographical distribution, represent a spread of both local and international manufacturing traditions. According to an elemental analysis, the material varies from iron to copper-tin, copper-lead and copper-tin-lead alloys. Clappers, pellets and pebbles prove that the bells and pellet bells were indisputably instruments intended for sound production. Clusters of small bell pendants, however, probably produced sound by jingling against each other. Spectrogram plots reveal that the partials of the still audible sounds range from 1 000 to 19 850 Hz. On the basis of 129 inhumation graves, hoards, barrows and stray finds, it seems evident that the bells, pellet bells and bell pendants were fastened to dresses and horse harnesses or carried in pouches and boxes. The resulting acoustic spaces could have been employed in constructing social hierarchies, since the instruments usually appear in richly furnished graves. Furthermore, the instruments repeatedly occur with crosses, edge tools and zoomorphic pendants that in the later Finnish-Karelian culture were regarded as prophylactic amulets. In the Iron Age as well as in later folk culture, the bell sounds seem to have expressed territorial, social and cosmological boundaries.

Pharmacogenetic Variation at CYP2D6, CYP2C9, and CYP2C19: Population Genetic and Forensic Aspects

Pharmacogenetics deals with genetically determined variation in drug response. In this context, three phase I drug-metabolizing enzymes, CYP2D6, CYP2C9, and CYP2C19, have a central role, affecting the metabolism of about 20-30% of clinically used drugs. Since genes coding for these enzymes in human populations exhibit high genetic polymorphism, they are of major pharmacogenetic importance. The aims of this study were to develop new genotyping methods for CYP2D6, CYP2C9, and CYP2C19 that would cover the most important genetic variants altering the enzyme activity, and, for the first time, to describe the distribution of genetic variation at these loci on global and microgeographic scales. In addition, pharmacogenetics was applied to a postmortem forensic setting to elucidate the role of genetic variation in drug intoxications, focusing mainly on cases related to tricyclic antidepressants, which are commonly involved in fatal drug poisonings in Finland. Genetic variability data were obtained by genotyping new population samples by the methods developed based on PCR and multiplex single-nucleotide primer extension reaction, as well as by collecting data from the literature. Data consisted of 138, 129, and 146 population samples for CYP2D6, CYP2C9, and CYP2C19, respectively. In addition, over 200 postmortem forensic cases were examined with respect to drug and metabolite concentrations and genotypic variation at CYP2D6 and CYP2C19. The distribution of genetic variation within and among human populations was analyzed by descriptive statistics and variance analysis and by correlating the genetic and geographic distances using Mantel tests and spatial autocorrelation. The correlation between phenotypic and genotypic variation in drug metabolism observed in postmortem cases was also analyzed statistically. The genotyping methods developed proved to be informative, technically feasible, and cost-effective. Detailed molecular analysis of CYP2D6 genetic variation in a global survey of human populations revealed that the pattern of variation was similar to those of neutral genomic markers. Most of the CYP2D6 diversity was observed within populations, and the spatial pattern of variation was best described as clinal. On the other hand, genetic variants of CYP2D6, CYP2C9, and CYP2C19 associated with altered enzymatic activity could reach extremely high frequencies in certain geographic regions. Pharmacogenetic variation may also be significantly affected by population-specific demographic histories, as seen within the Finnish population. When pharmacogenetics was applied to a postmortem forensic setting, a correlation between amitriptyline metabolic ratios and genetic variation at CYP2D6 and CYP2C19 was observed in the sample material, even in the presence of confounding factors typical for these cases. In addition, a case of doxepin-related fatal poisoning was shown to be associated with a genetic defect at CYP2D6. Each of the genes studied showed a distinct variation pattern in human populations and high frequencies of altered activity variants, which may reflect the neutral evolution and/or selective pressures caused by dietary or environmental exposure. The results are relevant also from the clinical point of view since the genetic variation at CYP2D6, CYP2C9, and CYP2C19 already has a range of clinical applications, e.g. in cancer treatment and oral anticoagulation therapy. This study revealed that pharmacogenetics may also contribute valuable information to the medicolegal investigation of sudden, unexpected deaths.

A capability-based view of organisational renewal : Combining opportunity- and advantage-seeking growth in large, established European and North American wood-industry companies

The purpose of this study was to extend understanding of how large firms pursuing sustained and profitable growth manage organisational renewal. A multiple-case study was conducted in 27 North American and European wood-industry companies, of which 11 were chosen for closer study. The study combined the organisational-capabilities approach to strategic management with corporate-entrepreneurship thinking. It charted the further development of an identification and classification system for capabilities comprising three dimensions: (i) the dynamism between firm-specific and industry-significant capabilities, (ii) hierarchies of capabilities and capability portfolios, and (iii) their internal structure. Capability building was analysed in the context of the organisational design, the technological systems and the type of resource-bundling process (creating new vs. entrenching existing capabilities). The thesis describes the current capability portfolios and the organisational changes in the case companies. It also clarifies the mechanisms through which companies can influence the balance between knowledge search and the efficiency of knowledge transfer and integration in their daily business activities, and consequently the diversity of their capability portfolio and the breadth and novelty of their product/service range. The largest wood-industry companies of today must develop a seemingly dual strategic focus: they have to combine leading-edge, innovative solutions with cost-efficient, large-scale production. The use of modern technology in production was no longer a primary source of competitiveness in the case companies, but rather belonged to the portfolio of basic capabilities. Knowledge and information management had become an industry imperative, on a par with cost effectiveness. Yet, during the period of this research, the case companies were better in supporting growth in volume of the existing activity than growth through new economic activities. Customer-driven, incremental innovation was preferred over firm-driven innovation through experimentation. The three main constraints on organisational renewal were the lack of slack resources, the aim for lean, centralised designs, and the inward-bound communication climate.

Molecular epidemiology of human rhinoviruses

The first part of this work investigates the molecular epidemiology of a human enterovirus (HEV), echovirus 30 (E-30). This project is part of a series of studies performed in our research team analyzing the molecular epidemiology of HEV-B viruses. A total of 129 virus strains had been isolated in different parts of Europe. The sequence analysis was performed in three different genomic regions: 420 nucleotides (nt) in the VP4/VP2 capsid protein coding region, the entire VP1 capsid protein coding gene of 876 nt, and 150 nt in the VP1/2A junction region. The analysis revealed a succession of dominant sublineages within a major genotype. The temporally earlier genotypes had been replaced by a genetically homogenous lineage that has been circulating in Europe since the late 1970s. The same genotype was found by other research groups in North America and Australia. Globally, other cocirculating genetic lineages also exist. The prevalence of a dominant genotype makes E-30 different from other previously studied HEVs, such as polioviruses and coxsackieviruses B4 and B5, for which several coexisting genetic lineages have been reported. The second part of this work deals with molecular epidemiology of human rhinoviruses (HRVs). A total of 61 field isolates were studied in the 420-nt stretch in the capsid coding region of VP4/VP2. The isolates were collected from children under two years of age in Tampere, Finland. Sequences from the clinical isolates clustered in the two previously known phylogenetic clades. Seasonal clustering was found. Also, several distinct serotype-like clusters were found to co-circulate during the same epidemic season. Reappearance of a cluster after disappearing for a season was observed. The molecular epidemiology of the analyzed strains turned out to be complex, and we decided to continue our studies of HRV. Only five previously published complete genome sequences of HRV prototype strains were available for analysis. Therefore, all designated HRV prototype strains (n=102) were sequenced in the VP4/VP2 region, and the possibility of genetic typing of HRV was evaluated. Seventy-six of the 102 prototype strains clustered in HRV genetic group A (HRV-A) and 25 in group B (HRV-B). Serotype 87 clustered separately from other HRVs with HEV species D. The field strains of HRV represented as many as 19 different genotypes, as judged with an approximate demarcation of a 20% nt difference in the VP4/VP2 region. The interserotypic differences of HRV were generally similar to those reported between different HEV serotypes (i.e. about 20%), but smaller differences, less than 10%, were also observed. Because some HRV serotypes are genetically so closely related, we suggest that the genetic typing be performed using the criterion "the closest prototype strain". This study is the first systematic genetic characterization of all known HRV prototype strains, providing a further taxonomic proposal for classification of HRV. We proposed to divide the genus Human rhinoviruses into HRV-A and HRV-B. The final part of the work comprises a phylogenetic analysis of a subset (48) of HRV prototype strains and field isolates (12) in the nonstructural part of the genome coding for the RNA-dependent RNA polymerase (3D). The proposed division of the HRV strains in the species HRV-A and HRV-B was also supported by 3D region. HRV-B clustered closer to HEV species B, C, and also to polioviruses than to HRV-A. Intraspecies variation within both HRV-A and HRV-B was greater in the 3D coding region than in the VP4/VP2 coding region, in contrast to HEV. Moreover, the diversity of HRV in 3D exceeded that of HEV. One group of HRV-A, designated HRV-A', formed a separate cluster outside other HRV-A in the 3D region. It formed a cluster also in the capsid region, but located within HRV-A. This may reflect a different evolutionary history of distinct genomic regions among HRV-A. Furthermore, the tree topology within HRV-A in the 3D region differed from that in the VP4/VP2, suggesting possible recombination events in the evolution of the strains. No conflicting phylogenies were observed in any of the 12 field isolates. Possible recombination was further studied using the Similarity and Bootscanning analyses of the complete genome sequences of HRV available in public databases. Evidence for recombination among HRV-A was found, as HRV2 and HRV39 showed higher similarity in the nonstructural part of the genome. Whether HRV2 and HRV39 strains - and perhaps also some other HRV-A strains not yet completely sequenced - are recombinants remains to be determined.

Surveillance of Surgical Site Infections following Major Hip and Knee Surgery in Finland

Background and aims. Since 1999, hospitals in the Finnish Hospital Infection Program (SIRO) have reported data on surgical site infections (SSI) following major hip and knee surgery. The purpose of this study was to obtain detailed information to support prevention efforts by analyzing SIRO data on SSIs, to evaluate possible factors affecting the surveillance results, and to assess the disease burden of postoperative prosthetic joint infections in Finland. Methods. Procedures under surveillance included total hip (THA) and total knee arthroplasties (TKA), and the open reduction and internal fixation (ORIF) of femur fractures. Hospitals prospectively collected data using common definitions and written protocol, and also performed postdischarge surveillance. In the validation study, a blinded retrospective chart review was performed and infection control nurses were interviewed. Patient charts of deep incisional and organ/space SSIs were reviewed, and data from three sources (SIRO, the Finnish Arthroplasty Register, and the Finnish Patient Insurance Centre) were linked for capture-recapture analyses. Results. During 1999-2002, the overall SSI rate was 3.3% after 11,812 orthopedic procedures (median length of stay, eight days). Of all SSIs, 56% were detected after discharge. The majority of deep incisional and organ/space SSIs (65/108, 60%) were detected on readmission. Positive and negative predictive values, sensitivity, and specificity for SIRO surveillance were 94% (95% CI, 89-99%), 99% (99-100%), 75% (56-93%), and 100% (97-100%), respectively. Of the 9,831 total joint replacements performed during 2001-2004, 7.2% (THA 5.2% and TKA 9.9%) of the implants were inserted in a simultaneous bilateral operation. Patients who underwent bilateral operations were younger, healthier, and more often males than those who underwent unilateral procedures. The rates of deep SSIs or mortality did not differ between bi- and uni-lateral THAs or TKAs. Four deep SSIs were reported following bilateral operations (antimicrobial prophylaxis administered 48-218 minutes before incision). In the three registers, altogether 129 prosthetic joint infections were identified after 13,482 THA and TKA during 1999-2004. After correction with the positive predictive value of SIRO (91%), a log-linear model provided an estimated overall prosthetic joint infection rate of 1.6% after THA and 1.3% after TKA. The sensitivity of the SIRO surveillance ranged from 36% to 57%. According to the estimation, nearly 200 prosthetic joint infections could occur in Finland each year (the average from 1999 to 2004) after THA and TKA. Conclusions. Postdischarge surveillance had a major impact on SSI rates after major hip and knee surgery. A minority of deep incisional and organ/space SSIs would be missed, however, if postdischarge surveillance by questionnaire was not performed. According to the validation study, most SSIs reported to SIRO were true infections. Some SSIs were missed, revealing some weakness in case finding. Variation in diagnostic practices may also affect SSI rates. No differences were found in deep SSI rates or mortality between bi- and unilateral THA and TKA. However, patient materials between these two groups differed. Bilateral operations require specific attention paid to their antimicrobial prophylaxis as well as to data management in the surveillance database. The true disease burden of prosthetic joint infections may be heavier than the rates from national nosocomial surveillance systems usually suggest.

Measurement of the tt̅ cross section in pp̅ collisions at √s=1.96 TeV using dilepton events with a lepton plus track selection

This paper reports a measurement of the cross section for the pair production of top quarks in ppbar collisions at sqrt(s) = 1.96 TeV at the Fermilab Tevatron. The data was collected from the CDF II detector in a set of runs with a total integrated luminosity of 1.1 fb^{-1}. The cross section is measured in the dilepton channel, the subset of ttbar events in which both top quarks decay through t -> Wb -> l nu b where l = e, mu, or tau. The lepton pair is reconstructed as one identified electron or muon and one isolated track. The use of an isolated track to identify the second lepton increases the ttbar acceptance, particularly for the case in which one W decays as W -> tau nu. The purity of the sample may be further improved at the cost of a reduction in the number of signal events, by requiring an identified b-jet. We present the results of measurements performed with and without the request of an identified b-jet. The former is the first published CDF result for which a b-jet requirement is added to the dilepton selection. In the CDF data there are 129 pretag lepton + track candidate events, of which 69 are tagged. With the tagging information, the sample is divided into tagged and untagged sub-samples, and a combined cross section is calculated by maximizing a likelihood. The result is sigma_{ttbar} = 9.6 +/- 1.2 (stat.) -0.5 +0.6 (sys.) +/- 0.6 (lum.) pb, assuming a branching ratio of BR(W -> ell nu) = 10.8% and a top mass of m_t = 175 GeV/c^2.

Three-year-olds are sensitive to semantic prominence during online language comprehension

Recent evidence from adult pronoun comprehension suggests that semantic factors such as verb transitivity affect referent salience and thereby anap- hora resolution. We tested whether the same semantic factors influence pronoun comprehension in young children. In a visual world study, 3-year- olds heard stories that began with a sentence containing either a high or a low transitivity verb. Looking behaviour to pictures depicting the subject and object of this sentence was recorded as children listened to a subsequent sentence containing a pronoun. Children showed a stronger preference to look to the subject as opposed to the object antecedent in the low transitivity condition. In addition there were general preferences (1) to look to the subject in both conditions and (2) to look more at both potential antecedents in the high transitivity condition. This suggests that children, like adults, are affected by semantic factors, specifically semantic prominence, when interpreting anaphoric pronouns.

Value Creation in Professional Service Processes. Propositions for Understanding Financial Value from a Customer Perspective

Many service management studies have suggested that service providers benefit from having long-term relationships with customers, but the argument from a customer perspective has been vague. However, especially in the business-to-business context, an analysis of financial value creation seems appropriate also from a customer perspective. Hence, the aim of this study is to develop a framework for understanding monetary value creation in professional service assignments from a customer perspective. The contribution of this study is an improved insight and framework for understanding financial value creation from a customer perspective in a professional service delivery process. The sources for monetary differences between transactional and long-term service providers are identified and quantified in case settings. This study contributes to the existing literature in service and relationship management by extending the customer’s viewpoint from perceived value to measurable monetary value. The contribution to the professional services lies in the process focus as opposed to the outcome focus, which is often accentuated in the existing professional services literature. The findings from the qualitative data suggest that a customer company may benefit from having an improved understanding of the service delivery (service assignment) process and the factors affecting the monetary value creation during the process. It is suggested that long-term relationships with service providers create financial value in the case settings in the short term. The findings also indicate that by using the improved understanding, a customer company can make more informed decisions when selecting a service provider for a specific assignment.

Kundklubbar och lojalitetsprogram i ett relationsmarknadsföringsperspektiv

Kundklubbar och lojalitetsprogram, marknadsföringsåtgärder som snabbt anammats inom de flesta branscher, utgör strategiska och taktiska åtaganden som direkt stöder en relationsmarknadsföringsansats i företag. Turistbranschen är inget undantag och idag ser vi hur även researrangörer utvecklat egna kundklubbar. Den frekvens med vilken finländska turister köper paketresor till "södern" per år ligger långt från den frekvens med vilken affärsresenärerna utnyttjar flygbolagens lojalitetsprogram. Trots det finns det ingen diskussion som belyser frågan hur väl relationsmarknadsföringsteorier utvecklade för marknader med hög köpfrekvens (flygbolagens lojalitetsprogram) är användbara på marknader där köpfrekvensen är lägre (t.ex. researrangörsbranschen). I denna artikel sammankopplas relationsmarknadsföringsteorier med teorier om lojalitetsprogram och kundklubbar. Artikeln syftar till att fördjupa förståelsen för lojalitetsprogrammens och kundklubbarnas relevans i en relationsmarknadsföringsansats. Ur diskussionen härleds forskningsfrågor som kan användas för att identifiera nya centrala forskningsområden. Artikeln fokuserar på den forskning som finner sin empiriska förankring i turistbranschen.

Heraproteiinivalmisteen vaikutus laihdutukseen ja laihdutustuloksen pysyvyyteen ylipainoisilla aikuisilla

Johdanto: Lihavuus on maailmalaajuisesti merkittävä kansanterveydellinen ja –taloudellinen ongelma. Lihavuuden ehkäisemiseksi ja epidemian leviämisen hillitsemiseksi on tärkeää tuntea lihavuuteen vaikuttavat tekijät. Yksittäisistä ruoka-aineista maidon käytön on havaittu monissa epidemiologisissa ja kokeellisissa tutkimuksissa olevan yhteydessä alhaisempaan painoon, ehkäisevän lihomista ja edistävän laihtumista. Maidon sisältämistä yhdisteistä kalsiumin vaikutuksia on tutkittu eniten. Myös heraproteiinin on esitetty olevan yksi mahdollinen painoon vaikuttava komponentti, ja näyttöä tästä on saatu eläinkokeista. Tavoitteet: Tutkimuksessa tavoitteena oli selvittää, vaikuttaako päivittäin nautittu heraproteiinia sisältävä välipalajuoma laihtumiseen tai saavutetun laihdutustuloksen pysyvyyteen ylipainoisilla aikuisilla. Aineisto ja menetelmät: Tutkimus toteutettiin osana Valio Oy:n OMPPU2-tutkimusta, joka oli satunnaistettu, lumekontrolloitu ja kaksoissokkoutettu kahden rinnakkaisen ryhmän tutkimus. Tutkimus alkoi rekrytoinneilla alkuvuodesta 2010, joissa tutkimukseen valittiin 105 ylipainoista (BMI 27–35), tervettä, 20–50-vuotiasta naista ja miestä. Tutkimushenkilöt satunnaistettiin tutkimus- ja verrokkiryhmiin, ja molemmat ryhmät nauttivat tutkimusvalmisteensa päivittäin hedelmätäysmehuun sekoitettuna (tutkimusryhmä heraproteiinijauheen ja verrokkiryhmä maltodekstriinijauheen). Tutkimus koostui kahdesta jaksosta: viiden kuukauden laihdutusjaksosta ja tätä seuranneesta kolmen kuukauden painonhallintajaksosta. Tutkimuskäynneillä tutkimuksen alussa, laihdutusjakson lopussa ja painonhallintajakson lopussa mitattiin tutkimushenkilöiden paino ja vyötärönympärys sekä määritettiin kehonkoostumus bioimpedanssilaitteella. Tutkimushenkilöiden ruoankäyttö ja ravinnonsaanti laskettiin samoissa aikapisteissä kerättyjen kolmen päivän ruokapäiväkirjojen perusteella. Tutkimushenkilöitä, joilla tutkimusvalmisteen käyttö oli alle 50 %, ei otettu huomioon tilastoanalyyseissä. Tilastollinen analyysi tehtiin käyttäen kahden riippumattoman otoksen t-testiä ja kaksisuuntaista parittaista t-testiä normaalijakautuneilla muuttujilla, ja Mann-Whitneyn U-testiä ja Wilcoxonin ttestiä ei-normaalijakautuneilla muuttujilla. Tutkimusvalmisteen ja painonmuutosten välinen korrelaatio laskettiin käyttäen Pearsonin korrelaatiokertoimia. Tulokset on ilmaistu keskiarvoina (keskihajonta). Tulokset: Molemmat ryhmät laihtuivat laihdutusjakson aikana. Heraproteiiniryhmässä painonpudotus oli 2,4 (3,8) kg (p=0,002) ja verrokkiryhmässä 3,4 (4,1) kg (p<0,001). Ryhmien välinen ero ei ollut merkitsevä. Rasvamassa väheni verrokkiryhmässä 2,4 (3,8) kg (p<0,001), mikä oli viiteellisesti enemmän (p=0,054) kuin heraproteiiniryhmässä 1,1 (3,1) kg (p=0,129). Rasvaprosentti ja viskeraalirasvan määrä pienenivät verrokkiryhmässä heraproteiiniryhmää enemmän (p<0,025). Vyötärönympärys pieneni heraproteiiniryhmässä 1,9 (3,0) cm (p=0,001) ja verrokkiryhmässä 3,8 (3,8) cm (p<0,001) ryhmien välisen eron ollessa merkitsevä (p=0,017). Maltodekstriinin käyttö korreloi käänteisesti painonmuutosten kanssa laihdutusjaksolla (r=-0,389, p=0,013). Painonhallintajaksolla painossa ei tapahtunut merkitseviä muutoksia kummassakaan ryhmässä. Heraproteiinin käytön ja painonmuutosten välisestä negatiivisesta korrelaatiosta oli viitteitä tällä jaksolla (r=-0,344, p=0,063). Kun tarkasteltiin koko tutkimuksen aikana tapahtuneita muutoksia (laihdutusjakson alusta painonhallintajakson loppuun), ei ryhmien välillä ollut merkitseviä eroja painon tai kehonkoostumuksen muutoksissa. Energiansaanti väheni molemmissa ryhmissä merkitsevästi laihdutusjakson aikana (p<0,01), mutta muutos ei eronnut ryhmien välillä. Ravintoaineista rasvan saanti väheni (p<0,001) ja C-vitamiinin saanti lisääntyi (p<0,001) molemmissa ryhmissä laihdutusjaksolla. Alkoholin saanti väheni verrokkiryhmässä (p=0,017). Proteiinin saanti lisääntyi heraproteiiniryhmässä merkitsevästi enemmän kuin verrokkiryhmässä (p=0,002). Painonhallintajaksolla energiansaanti ei muuttunut kummassakaan ryhmässä laihdutusjakson loppuun verrattuna. Fyysisessä aktiivisuudessa tutkimuksen aikana ei ollut eroa ryhmien välillä. Johtopäätökset: Heraproteiinin ei havaittu tehostavan laihdutusta maltodekstriiniin verrattuna tässä tutkimuksessa. Sen sijaan maltodekstriiniä nauttineessa ryhmässä rasvaprosentti ja erityisesti vatsan alueen rasva pienenivät heraproteiiniryhmää enemmän laihdutusjaksolla. Tulos oli lähes täysin vastakkainen tutkimushypoteesin kanssa, eikä vaikuttaisi selittyvän eroilla energiansaannissa tai fyysisessä aktiivisuudessa. Tämä tutkimus ei siis tue olettamusta, että heraproteiini osana laihdutusruokavaliota auttaisi laihdutuksessa. Painonhallintajaksolla heraproteiinin ja painonmuutosten välinen lähes merkitsevä käänteinen korrelaatio saattaa viitata heraproteiinin merkitykseen painonhallinnassa. Vapaasti elävien ihmisten kohdalla sekoittavia tekijöitä on kuitenkin vaikea vakioida, mikä vaikeuttaa johtopäätösten tekemistä.
