Ataque de Lonomia sp. (Lepidoptera: Saturniidae) em seringueira no município de Bujari, AC.

Os estudos dos insetos associados às culturas agrícolas e florestais são dinâmicos, em função da evolução dos sistemas de cultivo, do avanço da fronteira agrícola, da introdução de novas pragas e da resistência aos produtos químicos historicamente aplicados. Nesse contexto, os avanços nos estudos dos insetos-praga periodicamente precisam ser integrados em publicações de referência, que permitam fácil acesso a esses conhecimentos. Assim, o objetivo desta publicação é documentar o ataque de lagartas do gênero Lonomia, popularmente conhecidas como lagartas-de-fogo, causando intensa desfolha em cultivos de seringueira (Hevea brasiliensis) no Acre. Há um grande número de trabalhos publicados sobre esse gênero, no que tange aos problemas acarretados pelo contato direto de pessoas com as lagartas, provocando acidentes hemorrágicos graves, dependendo da área lesionada e da extensão do contato. No entanto, não havia relatos dessas lagartas causando intenso desfolhamento em seringais de cultivo, ocasionando prejuízos econômicos. A partir da intensificação do cultivo, surtos populacionais de insetos, considerados pragas secundárias em muitas culturas, podem acontecer com mais frequência, necessitando de conhecimento e estratégias de manejo que visem ao monitoramento, distribuição e controle de populações de insetos no Estado do Acre, a fim de prevenir surtos populacionais de pragas e, consequentemente, prejuízos elevados aos produtores acrianos.

Low-level laser therapy and light-emitting diode effects in the secretion of neuropeptides SP and CGRP in rat skin

The phototherapy effects in the skin are related to biomodulation, usually to accelerate wound healing. However, there is no direct proof of the interrelation between the effects of low-level laser therapy (LLLT) and light-emitting diode (LED) in neuropeptide secretion, these substances being prematurely involved in the neurogenic inflammation phase of wound healing. This study therefore focused on investigating LLLT and LED in Calcitonin gene-related peptide (CGRP) and substance P (SP) secretion in healthy rat skin. Forty rats were randomly distributed into five groups with eight rats each: Control Group, Blue LED Group (470 nm, 350 mW power), Red LED Group (660 nm, 350 mW power), Red Laser Group (660 nm, 100 mW power), and Infrared Laser Group (808 nm, 100 mW power) (DMCA (R) Equipamentos Ltda., So Carlos, So Paulo, Brazil). the skin of the animals in the experimental groups was irradiated using the punctual contact technique, with a total energy of 40 J, single dose, standardized at one point in the dorsal region. After 14 min of irradiation, the skin samples were collected for CGRP and SP quantification using western blot analysis. SP was released in Infrared Laser Group (p = 0.01); there was no difference in the CGRP secretion among groups. Infrared (808 nm) LLLT enhances neuropeptide SP secretion in healthy rat skin.

Reaction time and replenishment time of SP and CGRP after incision in rat skin

Background. the skin neurogenic inflammation is mainly related to Substance P (SP) and Calcitonin Gene-related Peptide (CGRP). There is no data on their availability in the dynamics of skin nerve endings, concerning their release and replenishment after a nociceptive stimulus, so this was investigated. Materials and methods. 25 rats were randomly distributed in 5 groups. the animals of the control group (CG) determined the baseline levels of neuropeptides in the skin. the groups S0 and S30 did not receive any cutaneous stimulus at 30 and 60 minutes, respectively. in the group S1, an incision stimulus was made at 30 minutes. in the group S31, a nociceptive stimulus was performed by subdermal scratching at 30 minutes and, at 60 minutes, the incision stimulus was carried out in the same location (nociceptive hyperstimulation). the skin samples of the other animals were harvested from the back 1 minute after their death. SP, pro-CGRP and CGRP were quantified by Western Blotting. Results. the incision stimulus released SP, S1 compared to S0 (p < 0.05) detected in the first minute, and the replenishment time was more than 30 minutes. Also, it cleaved pro-CGRP, S1 compared to S31 (p < 0.05) in the first minute, and its replenishment time less than 30 minutes. Release of CGRP was not detected. Conclusion. the incision released SP already detected in the first minute; its replenishment time is more than 30 minutes. the incision decreased pro-CGRP, also detected in the first minute; and its replenishment time is less than 30 minutes.

Sprzeczność z umową (statutem) spółki jako przesłanka uchylenia uchwały zgromadzenia spółki kapitałowej

Artykuł zatytułowany „Sprzeczność z umową (statutem) spółki jako przesłanka uchylenia uchwały zgromadzenia spółki kapitałowej” dotyka jednego z najciekawszych zagadnień prawa handlowego, jakim niewątpliwie jest zaskarżanie uchwał zgromadzeń spółek kapitałowych. W niniejszym artykule autorzy skupili się na przedstawieniu jednej z przesłanek wniesienia powództwa o uchylenie sprzecznej z normami pozaustawowymi uchwały zgromadzenia spółki kapitałowej. W związku z lakonicznym brzmieniem art. 249 i 422 k.s.h. zagadnienie to wywołuje wiele kontrowersji interpretacyjnych, do których autorzy odnoszą się przywołując liczne orzeczenia sądów oraz głosy przedstawicieli doktryny. W szczególności rozważeniu podlega niesamoistny charakter przedmiotowej przesłanki, a także problemy związane z wpływem naruszeń formalnych na treść podejmowanej uchwały. Ponadto, postawione zostaje – aktualne w kontekście najnowszych wypowiedzi doktryny – pytanie o granicę pomiędzy naruszeniem postanowień konstytucji spółki a norm dyspozytywnych powszechnie obowiązującego prawa.

Discoplana malagasensis sp. nov. a New Turbellarian (Platyhelminthes: Polycladida: Leptoplanidae) symbiotic in an ophiuroid (Echinodermata), with a cladistic analysis of the Discoplana/Euplana species

A new species of polyclad flatworm from Papua New Guinea is described. It is found symbiotic in the ophiuroid Ophiothrix purpurea von Martens, 1867 (Echinodermata: Ophiuroidea). Apparently it belongs to the taxon Discoplana Bock, 1913 and can be distinguished from the six previously described Discoplana species by its very short ejaculatory duct and a penial papilla covered with a penial sheath, but without any true sclerotised structures such as a stylet or spines. The cladistic analysis of the Discoplana/Euplana species, based on morphological features and including two outgroups, reveals that all species of Discoplana, except D. pacificola, form a monophyletic taxon, that is not a synonym of Euplana Girard, 1893. Therefore the name Discoplana is conserved and the new species will be described as Discoplana malagasensis sp. nov. A key for the Discoplana/Euplana group is provided. In this key the biogeographical distribution and possible synonyms are given.
