First record of Molorchus minor minor (Linnaeus) (Coleoptera, Cerambycidae) in Brazil

Molorchus minor minor (Linnaeus) (Coleoptera, Cerambycidae) is recorded for the first time in Brazil (Bahia). It was originally described from Europe and is currently widely distributed in that continent and Asia.

Poststroke fatigue following minor infarcts: a prospective study.

OBJECTIVE: To explore the potential relationship between fatigue following strokes and poststroke mood, cognitive dysfunction, disability, and infarct site and to determine the predictive factors in the development of poststroke fatigue (PSF) following minor infarcts. METHODS: Ninety-nine functionally active patients aged less than 70 years with a first, nondisabling stroke (NIH Stroke Scale score ≤6 in acute phase and ≤3 after 6 months, modified Rankin Scale score ≤1 at 6 months) were assessed during the acute phase and then at 6 (T1) and 12 months (T2) after their stroke. Scores in the Fatigue Assessment Inventory were described and correlated to age, gender, neurologic and functional impairment, lesion site, mood scores, neuropsychological data, laboratory data, and quality of life at T1 and T2 using a multivariate logistic regression analysis in order to determine which variables recorded at T1 best predicted fatigue at T2. RESULT: As many as 30.5% of the patients at T1 and 34.7% at T2 (11.6% new cases between T1 and T2) reported fatigue. At both 6 and 12 months, there was a significant association between fatigue and a reduction in professional activity. Attentional-executive impairment, depression, and anxiety levels remained associated with PSF throughout this time period, underlining the critical role of these variables in the genesis of PSF. There was no significant association between the lesion site and PSF. CONCLUSION: This study suggests that attentional and executive impairment, as well as depression and anxiety, may play a critical role in the development of PSF.

NMR and LC-MSn characterisation of two minor saponins from Ilex paraguariensis.

Two minor saponins obtained from the methanolic extract of the leaves of Ilex paraguariensis have been characterised by 13C-NMR, 1H-NMR, API-MS and chemical hydrolysis as oleanolic acid-3-O-(beta-D-glucopyranosyl-(1-->3)-alpha-L-arabinopyranosyl)-(28-->1)- beta-D-glucopyranosyl ester (guaiacin B) and oleanolic acid-3-O-(beta-D-glucopyranosyl-(1-->3)-(alpha-L-rhamnopyranosyl- (1-->2))-alpha-L-arabinopyranosyl)-(28-->1)-beta-D-glucopyranosyl ester (nudicaucin C). Both are isomeric forms of the known matesaponins 1 (MSP 1) and 2 (MSP 2) and differ only by the nature of the aglycone: they have oleanolic acid instead of ursolic acid, as found in the matesaponins. These minor saponins have not been fully separated from their major isomers MSP 1 and 2 and were characterised by in-mixture NMR analysis, LC-MS and LC-MSn experiments.

Clinical consequences of sensitisation to minor histocompatibility antigens before allogeneic bone marrow transplantation.

To study sensitisation to minor histocompatibility antigens (mHag) before and after BMT, we measured antidonor CTL activity in five patients who had rejected their graft, and in a control group of 10 leukemic patients who engrafted without complications. All patients were transplanted with marrow from an HLA-identical sibling. Fourteen patients were conditioned with cyclophosphamide (120 mg/kg) and TBI (1350 cGy) and received a T cell-depleted graft, while one patient with aplastic anaemia received cyclophosphamide alone and unmanipulated marrow. Before transplantation, anti-donor CTL activity was detected in two of the 15 patients. These patients rejected their grafts at days 21 and 58, respectively. In the other three patients who rejected their grafts at days 41, 60 and 250, CTL activity was found only after transplantation. In contrast, no anti-donor CTLs could be detected at any time in the 10 patients who engrafted permanently. We have identified some of the mHags recognised during graft rejection by cloning and subsequent specificity analysis of the recipient CTLs. In the patient who rejected at day 41 without detectable immunisation before BMT, the response was directed against HA-1, a minor antigen known to play a role in GVHD. In the other combinations, a significant part of the CTL activity was directed against the male antigen H-Y. In the patient who rejected the marrow of her HLA-identical brother at day 250, two clones recognised H-Y, while five others recognised at least three distinct autosomal mHags. This patient had an HLA-identical sister who expressed only one autosomal mHag that had been recognised by one single T cell clone. After re-transplantation with the marrow of this second donor, the CTL activity could no longer be detected and the patient engrafted without further complications.

Glucose release from GLUT2-null hepatocytes: characterization of a major and a minor pathway.

We previously reported that glucose can be released from GLUT2-null hepatocytes through a membrane traffic-based pathway issued from the endoplasmic reticulum. Here, we further characterized this glucose release mechanism using biosynthetic labeling protocols. In continuous pulse-labeling experiments, we determined that glucose secretion proceeded linearly and with the same kinetics in control and GLUT2-null hepatocytes. In GLUT2-deficient hepatocytes, however, a fraction of newly synthesized glucose accumulated intracellularly. The linear accumulation of glucose in the medium was inhibited in mutant, but not in control, hepatocytes by progesterone and low temperature, as previously reported, but, importantly, also by microtubule disruption. The intracellular pool of glucose was shown to be present in the cytosol, and, in pulse-chase experiments, it was shown to be released at a relatively slow rate. Release was not inhibited by S-4048 (an inhibitor of glucose-6-phosphate translocase), cytochalasin B, or progesterone. It was inhibited by phloretin, carbonyl cyanide p-(trifluoromethoxy)phenylhydrazone, and low temperature. We conclude that the major release pathway segregates glucose away from the cytosol by use of a membrane traffic-based, microtubule-dependent mechanism and that the release of the cytosolic pool of newly synthesized glucose, through an as yet unidentified plasma membrane transport system, cannot account for the bulk of glucose release.

A program of nurse algorithm-guided care for adult patients with acute minor illnesses in primary care

Background: Attention to patients with acute minor-illnesses requesting same-day consultation represents a major burden in primary care. The workload is assumed by general practitioners in many countries. A number of reports suggest that care to these patients may be provided, at in least in part, by nurses. However, there is scarce information with respect to the applicability of a program of nurse management for adult patients with acute minor-illnesses in large areas. The aim of this study is to assess the effectiveness of a program of nurse algorithm-guided care for adult patients with acute minor illnesses requesting same-day consultation in primary care in a largely populated area. Methods: A cross-sectional study of all adult patients seeking same day consultation for 16 common acute minor illnesses in a large geographical area with 284 primary care practices. Patients were included in a program of nurse case management using management algorithms. The main outcome measure was case resolution, defined as completion of the algorithm by the nurse without need of referral of the patient to the general practitioner. The secondary outcome measure was return to consultation, defined as requirement of new consultation for the same reason as the first one, in primary care within a 7-day period. Results: During a two year period (April 2009-April 2011), a total of 1,209,669 consultations were performed in the program. Case resolution was achieved by nurses in 62.5% of consultations. The remaining cases were referred to a general practitioner. Resolution rates ranged from 94.2% in patients with burns to 42% in patients with upper respiratory symptoms. None of the 16 minor illnesses had a resolution rate below 40%. Return to consultation during a 7-day period was low, only 4.6%. Conclusions: A program of algorithms-guided care is effective for nurse case management of patients requesting same day consultation for minor illnesses in primary care.

Association of major and minor ECG abnormalities with coronary heart disease events.

CONTEXT: In populations of older adults, prediction of coronary heart disease (CHD) events through traditional risk factors is less accurate than in middle-aged adults. Electrocardiographic (ECG) abnormalities are common in older adults and might be of value for CHD prediction. OBJECTIVE: To determine whether baseline ECG abnormalities or development of new and persistent ECG abnormalities are associated with increased CHD events. DESIGN, SETTING, AND PARTICIPANTS: A population-based study of 2192 white and black older adults aged 70 to 79 years from the Health, Aging, and Body Composition Study (Health ABC Study) without known cardiovascular disease. Adjudicated CHD events were collected over 8 years between 1997-1998 and 2006-2007. Baseline and 4-year ECG abnormalities were classified according to the Minnesota Code as major and minor. Using Cox proportional hazards regression models, the addition of ECG abnormalities to traditional risk factors were examined to predict CHD events. MAIN OUTCOME MEASURE: Adjudicated CHD events (acute myocardial infarction [MI], CHD death, and hospitalization for angina or coronary revascularization). RESULTS: At baseline, 276 participants (13%) had minor and 506 (23%) had major ECG abnormalities. During follow-up, 351 participants had CHD events (96 CHD deaths, 101 acute MIs, and 154 hospitalizations for angina or coronary revascularizations). Both baseline minor and major ECG abnormalities were associated with an increased risk of CHD after adjustment for traditional risk factors (17.2 per 1000 person-years among those with no abnormalities; 29.3 per 1000 person-years; hazard ratio [HR], 1.35; 95% CI, 1.02-1.81; for minor abnormalities; and 31.6 per 1000 person-years; HR, 1.51; 95% CI, 1.20-1.90; for major abnormalities). When ECG abnormalities were added to a model containing traditional risk factors alone, 13.6% of intermediate-risk participants with both major and minor ECG abnormalities were correctly reclassified (overall net reclassification improvement [NRI], 7.4%; 95% CI, 3.1%-19.0%; integrated discrimination improvement, 0.99%; 95% CI, 0.32%-2.15%). After 4 years, 208 participants had new and 416 had persistent abnormalities. Both new and persistent ECG abnormalities were associated with an increased risk of subsequent CHD events (HR, 2.01; 95% CI, 1.33-3.02; and HR, 1.66; 95% CI, 1.18-2.34; respectively). When added to the Framingham Risk Score, the NRI was not significant (5.7%; 95% CI, -0.4% to 11.8%). CONCLUSIONS: Major and minor ECG abnormalities among older adults were associated with an increased risk of CHD events. Depending on the model, adding ECG abnormalities was associated with improved risk prediction beyond traditional risk factors.

Papillary cystoadenoma lymphomatosum (Warthin-like) of minor salivary glands

Papillary cystadenoma lymphomatosum is a benign salivary gland tumor most frequently located in the parotid gland (Warthin"s tumor). Its presentation in other major, or in minor, salivary glands is rare. Clinically, it manifests as a slow growing tumor, fluctuant on palpation due to its cystic morphology. The treatment of choice is complete excision with wide tumor-free margins. We present a 73-year-old female patient with an asymptomatic tumor of 8 years evolution in the right posterior area of the hard palate. We performed surgical excision and a biopsy, which was reported as papillary cystadenoma lymphomatosum. During the post-operative examination carried out after 3 weeks, it was observed that the lesion had recurred. The lesion was re-operated, performing the excision with CO2 laser and including the periosteum to ensure complete resection of the tumor. At 10 months follow-up, there was no recurrence of the lesion. This article includes a review of this condition and discusses its most important clinical and pathologic features and therapeutic approaches.

Minor salivary gland tumors: a clinicopathological study of 18 cases

Introduction: Minor salivary gland tumors (MSGTs) are infrequent, representing 10-15% of all salivary neoplasms. Despite this low frequency, MSGTs conform a heterogeneous group of neoplasms characterized by a broad range of histological types. Patients and method: We identified cases of MSGT in a retrospective study of the biopsies made in the period 1997-2007 in the Service of Oral Surgery (Dental Clinic of the University of Barcelona, Spain). The data collected comprised patient age and sex, the clinical characteristics and location of the tumor, the duration of the lesion, its size, the treatment provided, and the histopathological findings. Results: Of the 18 cases of MSGT studied, 12 corresponded to women (66.7%) and 6 to men (33.3%). The great majority (94.4%) were benign tumors. The preferential location was the posterior third of the hard palate (33.2%), followed by the soft palate (16.7%) and the mucosa of the upper lip (16.7%). The histopathological diagnoses of our MSGTs comprised 10 pleomorphic adenomas (55.3%), 2 cystadenomas (11.1%), 1 myoepithelioma (5.6%), 1 sialadenoma papilliferum (5.6%), 1 basal cell adenoma (5.6%), 1 Warthin"s tumor (5.6%), 1 canalicular adenoma (5.6%), and 1 low-grade polymorphic adenocarcinoma (5.6%). Discussion and conclusions: Coinciding with our own results, the literature describes a high recurrence rate for MSGTs (5-30%) when surgical removal is incomplete. Six percent of all benign minor salivary gland tumors are considered to relapse, versus 65% of all malignant lesions. Periodic clinical controls are required, since the possibility of malignant transformation must be taken into account

A minimal i-motif stabilized by minor groove G:T:G:T tetrads

The repetitive DNA sequences found at telomeres and centromeres play a crucial role in the structure and function of eukaryotic chromosomes. This role may be related to the tendency observed in many repetitive DNAs to adopt non-canonical structures. Although there is an increasing recognition of the importance of DNA quadruplexes in chromosome biology, the co-existence of different quadruplex-forming elements in the same DNA structure is still a matter of debate. Here we report the structural study of the oligonucleotide d(TCGTTTCGT) and its cyclic analog d. Both sequences form dimeric quadruplex structures consisting of a minimal i-motif capped, at both ends, by a slipped minor groove-aligned G:T:G:T tetrad. These mini i-motifs, which do not exhibit the characteristic CD spectra of other i-motif structures, can be observed at neutral pH, although they are more stable under acidic conditions. This finding is particularly relevant since these oligonucleotide sequences do not contain contiguous cytosines. Importantly, these structures resemble the loop moiety adopted by an 11-nucleotide fragment of the conserved centromeric protein B (CENP-B) box motif, which is the binding site for the CENP-B.
