Pterygium management and comparison of different surgical approaches with supportive treatment in Rural Maharashtra

Background:Numerous surgical procedures and changes have been ineffective in preventing the recurrence of pterygium. Aprospective clinical observational analysis of 205 individuals with primary pterygium was conducted where patients were treated with various surgical procedures. The patients were observed for two to five years in order to examine the frequency of recurrences and consequences. Result: Patients were divided into four groups and treated using a variety of surgical methods. Straightforward excision of pterygium was the treatment of choice in group 1. Excision with conjunctival rotation pedicle graft was used on patients in Group 2. Excision and conjunctival autograft were used to treat Group 3 patients. Patients in Group 4 received excision and a 0.02 percent solution of mitomycin c drops as a postoperative treatment. Age varied from 22 to 58, with a median of 34. All four groups had an equal number of men and women. Hemorrhage, astigmatism, symblepheron, foreign body feeling, and a corneo-scleral ulcer were among complications that were reported. There were 12 percent complications in group 1, 16 percent complications in group 2, 6 percent complications in group 3, and 8 percent complications in group 4. Criteria for recurrence was defined as the regrowth of fibrovascular tissue or the appearance of an aesthetic flaw. It's 30 percent for group 1; 14 percent for group 2, 9 per cent for group 3, and 8 per cent for group 4. Conclusion: The least rate of recurrence was noted in patients of Group 4 who had pterygium excision with postoperative mitomycin c instillation, and complications were least common in patients in Group 3 who had pterygium resection with conjunctival autograft

A Cadaveric Study of Palmaris Longus Muscle

Background: Aim: To assess the palmaris longus muscle.Methods:40 formalin fixed cadavers of both genders were included. Routine dissection of the upper limb was carried following the Cunnigham抯 Manual of Practical Anatomy. During the dissection of the anterior compartment of forearm, the Palmaris longus muscle was identified & carefully dissected.Results:Out of 40 cadavers, 22 were of males and 18 were of females. Morphology of Palmaris longus found to be normal in 18, agenesis in 6, fusiform in 4, hybrid in 6, bifurcated tendon in 5 and fleshy in 1 case. A significant difference was observed (P< 0.05).Conclusions:Surgeon must be aware of the variations of palmaris longus muscle. Morphology of Palmaris longus found to be normal, agenesis, fusiform, hybrid, bifurcated tendon and fleshy.

Marker-trait association analysis for weight of first and second fleshy root in 126 diverse lines of aconitum carmichaelii / 中草药

Objective To identify molecular markers associated with weight of fleshy root of Aconitum carmichaelii, and provide technologic basis to A. carmichaelii breeding. Methods The marker-trait association (MTA) analysis for the weight of first and second fleshy root was conducted in association mapping panel comprised 126 diverse lines based on 280 AFLP loci. Results The population structure analysis of all lines conducted using STRUCTURE indicated that the likely number of subgroups was 2 based on the change in k. A total of 19 loci were identified to associate with 0.87%-6.69% of phenotypic variance for objective trait. The loci of P1M1-27, P3M3-30, and P1M1-20 were identified under all analysis modes of GLM, MLM, GLM + K, and GLM + Q. Conclusion These loci should be compatible to marker assistance selection during A. carmichaelii breeding.

Anatomical Variation of Palmaris Longus: Tendinous Origin and Fleshy Insertion.

A tendinous origin and fleshy insertion of palmaris longus muscle was observed in the left forearm during routine dissection which was performed on adult male cadaver in the department of Anatomy, Dr. Rajendra Prasad Government Medical College. It was having long tendinous origin from the medial epicondyle of the humerus and the surrounding deep fascia. It was fusiform at the lower middle of the forearm. The fleshy muscular insertion was noted to the flexor retinaculum and few muscular fibers interdigitate with flexor carpi ulnaris muscle and palmar aponeurosis. The length of tendon was 19 inches and fleshy muscular length was 11inches. Themedian nerve and ulnar nervewas covered by this fleshy insertion. This palmaris longus variation is helpful for the surgeon and the radiologist, orthopaedic, plastic surgeon during any diagnosis of the forearm because this fleshy part of muscle can compress the median nerve and ulnar nerve or it can be mistaken as a tumor or ganglion during radiological or clinical examination.

Fructification phenology as an important tool in the recovery of iron mining areas in Minas Gerais, Brazil / Fenologia da frutificação como importante ferramenta na recuperação de áreas de mineração de ferro em Minas Gerais, Brasil

"Canga" is a name given to the ferruginous rocky fields that can be found in the "Quadrilátero Ferrífero" of Minas Gerais, Brazil. The endemism and species richness make them areas of special biological importance, regarded as high-priority for conservation. Nevertheless, they are being threatened by intense mining activity. Aiming to understand more about this flora, this study was performed in order to determine the maturation or dispersal period of the fruits of four Canga species, Alibertia vaccinioides K.Schum. (Rubiaceae), Coccoloba acrostichoides Cham. (Polygonaceae), Miconia sellowiana Naudin (Melastomataceae), and one probable new species of Calyptranthes Sw. (Myrtaceae). Although fruit maturation or dispersal tended to occur at the end of the dry season, some asynchrony was observed in these species, with food sources being available during most of the year. This shows that these species have the potential to attract animals the whole year round, and planting them for the recovery of iron mining areas may increase the community's self-regeneration capacity, leading to a more successful restoration process.

Canga é um nome dado para os campos rupestres ferruginosos encontrados no Quadrilátero Ferrífero de Minas Gerais. O endemismo e riqueza de espécies os tornam uma área de importância biológica especial, considerada prioritária para conservação. Além disso, tem sido submetida à intensa atividade mineradora. Este estudo objetivou determinar as épocas de maturação/dispersão de frutos de quatro espécies de ocorrência na canga, Alibertia vaccinioides K. Schum. (Rubiaceae), Coccoloba acrostichoides Cham. (Polygonaceae), Miconia sellowiana Naudin (Melastomataceae) e de uma provável espécie nova de Calyptranthes Sw. (Myrtaceae). Apesar da maturação/dispersão dos frutos ter apresentado uma tendência de ocorrer no final da estação seca, foi constatada uma assincronia do evento entre essas espécies, com disponibilidade de alimento aos animais frugívoros ao longo de grande parte do ano. O plantio dessas espécies para recuperação de áreas ferruginosas similares degradadas pela mineração poderá atrair fauna durante todas as estações, aumentando o potencial de autorregeneração da comunidade e o consequente sucesso no processo de restauração.

Consumo de frutos e abundância de Tucano Toco (Ramphastos toco) em dois hábitats do Pantanal Sul / Toco Toucan (Ramphastos toco) frugivory and abundance in two habitats at South Pantanal

Tucano Toco (Ramphastos toco) é um dos grandes frugívoros de dossel, tanto de florestas contínuas quanto ambientes semi-abertos. No Pantanal Sul o Tucano Toco é comum em paisagens que intercalam ambientes fechados e abertos. Neste estudo avaliamos a abundância de Tucano Toco em capões de mata e mata ciliar, bem como a produção e consumo de frutos carnosos durante a estação seca. Apenas seis espécies frutificaram em capões de mata, e cinco em mata ciliar. Nos capões de mata a maior abundância do gênero Ficus, cuja frutificação foi assincrônica, proporcionou disponibilidade constante de frutos. Na mata ciliar a oferta de frutos carnosos foi variável e as figueiras foram raras e não foram detectadas pelo método de quadrante centrado. Nos dois hábitats os tucanos exploraram frutos de Cecropia pachystachya, Genipa americana e Ficus. A ocorrência de Tucano Toco foi sempre maior em capões de mata do que em mata ciliar, sendo mais elevada em um dado hábitat, quando pelo menos duas espécies disponibilizavam frutos carnosos. A maior regularidade na ocorrência dos tucanos em capões de mata pode ter sido conseqüência da oferta constante de frutos carnosos, a qual ocorreu devido à presença das espécies do gênero Ficus neste hábitat. Porém, a presença da espécie nos hábitats avaliados deve decorrer da combinação de todos os frutos comuns na sua alimentação.

Toco Toucan (Ramphastos toco) is one of the largest frugivorous birds of canopy, even in continuous forests than in semi-opened habitat. At South Pantanal (Brazil) Toco toucan is common in landscapes that intersperse open and closed habitats. On this research we evaluated the Toco Toucan abundance in capões forest and gallery forest as well as the production and consumption of fleshy fruit during dry season. Only six species produced fruits in capões forests, and five in gallery forests. In capões forest the higher presence of Ficus genera, which fructifying was asynchronous, provided constant fruit source. In gallery forests where fig trees were rare, the abundance of fleshy fruits was variable. The toucans explored Cecropia pachystachya, Genipa americana and Ficus fruits at two habitats. The occurrence of Toco Toucan in capões forest always was higher than in gallery forest. The occurrence in each habitat was higher when at least two species produced fleshy fruits at the same time. The regular toucan occurrence at capões forest was potentially a consequence of constant fleshy fruit availability, which occurred due to the presence of Ficus species in this habitat. However, the presence of Toco Toucan at this habitat must result from the combination of all common fruits in bird feed.
