RESUMO
Termites are known as social insects worldwide. Presently in China 473 species, 44 genera and 4 families of termites have been reported. Of them, 111 Reticulitermes species are widely spread in different zones of China. The dispersion flight season of these Chinese Reticulitermes species are usually started from February to June, but in some regions different species are distributed, sharing their boundaries and having overlapping flight seasons. These reasons become important sources of hybridization between two different heterospecific populations of termites. It was confirmed that the fertilized eggs and unfertilized eggs of some Reticulitermes termites have the capacity of cleavage. While the unfertilized eggs of R. aculabialis, R. chinensis and R. labralis cleaved normally and the only R. aculabialis unfertilized eggs develop in embryos. While, the R. flaviceps and R. chinensis were observed with their abnormal embryonic development, and not hatching of eggs parthenogenetically. They were reported more threatening to Chinese resources as they propagate with parthenogenesis, hybridization and sexual reproduction. Eggshell and macrophiles of eggs play important roles in species identification and control. Although, they are severe pests and cause a wide range of damages to wooden structures and products in homes, buildings, building materials, trees, crops, and forests in China's Mainland.
Os cupins são conhecidos como insetos sociais em todo o mundo. Atualmente na China foram relatadas 473 espécies, 44 gêneros e 4 famílias de cupins. Destas, 111 espécies de Reticulitermes estão amplamente distribuídas em diferentes zonas da China. A temporada de voo de dispersão dessas espécies chinesas de Reticulitermes geralmente começa de fevereiro a junho, mas em algumas regiões diferentes espécies são distribuídas, compartilhando seus limites e tendo temporadas de voo sobrepostas. Essas razões tornam-se importantes fontes de hibridização entre duas populações heteroespecíficas de cupins. Foi confirmado que os ovos fertilizados e não fertilizados de alguns cupins Reticulitermes possuem capacidade de clivagem. Já os ovos não fertilizados de R. aculabialis, R. chinensis e R. labralis clivaram normalmente, e os únicos ovos não fertilizados de R. aculabialis se desenvolvem em embriões. R. flaviceps e R. chinensis foram observados com desenvolvimento embrionário anormal, e não eclosão de ovos por partenogênese. Eles foram relatados como mais ameaçadores para os recursos chineses à medida que se propagam com partenogênese, hibridização e reprodução sexual. Casca de ovo e macrófilos de ovos desempenham papéis importantes na identificação e controle de espécies, embora sejam pragas graves e causem uma ampla gama de danos a estruturas e produtos de madeira em residências, edifícios, materiais de construção, árvores, plantações e florestas na China continental.

Abstract Cucumber mosaic virus (CMV) is a tremendous threat to vegetables across the globe, including in Pakistan. The present work was conducted to investigate the genetic variability of CMV isolates infecting pea and spinach vegetables in the Pothwar region of Pakistan. Serological-based surveys during 2016-2017 revealed 31.70% overall CMV disease incidence from pea and spinach crops. Triple-antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA) revealed that all the positive isolates belong to CMV subgroup II. Two selected cDNA from ELISA-positive samples representing each pea and spinach crops were PCR-amplified (ca.1100 bp) and sequenced corresponding to the CMV CP gene which shared 93.7% nucleotide identity with each other. Both the sequences of CMV pea (AAHAP) and spinach (AARS) isolates from Pakistan were submitted to GenBank as accession nos. MH119071 and MH119073, respectively. BLAST analysis revealed 93.4% sequence identity of AAHAP isolate with SpK (KC763473) from Iran while AARS isolate shared maximum identity (94.5%) with the strain 241 (AJ585519) from Australia and clustered with some reference isolates of CMV subgroup II from UK (Z12818) and USA (AF127976) in a Neighbour-joining phylogenetic reconstruction. A total of 59 polymorphic (segregating) sites (S) with nucleotide diversity (π) of 0.06218 was evident while no INDEL event was observed in Pakistani isolates. The evolutionary distance of Pakistani CMV isolates was recorded as 0.0657 with each other and 0.0574-0.2964 with other CMV isolates reported elsewhere in the world. A frequent gene flow (Fst = 0.30478 <0.33) was observed between Pakistani and earlier reported CMV isolates. In genetic differentiation analysis, the value of three permutation-based statistical tests viz; Z (84.3011), Snn (0.82456), and Ks* (4.04042) were non-significant. The statistical analysis revealed the values 2.02535, 0.01468, and 0.71862 of Tajima's D, Fu, & Li's F* and D* respectively, demonstrating that the CMV population is under balancing selection.

RESUMO
Filariasis is a condition resulting from filarial parasites that affects both humans and animals.There are several hundreds of filarial parasites which have been mentioned in medical literature, out of which only eight species are known to cause natural infections in humans. Repeated episodes of inflammation and lymphedema cause lymphatic damage, persistent edema, and elephantiasis of the legs, arms, scrotum, vulva, and breasts. We have reported two cases of filariasis at unusual sites
RESUMO
Vegetables are an important source of income and high-value crops for small farmers. Chilli (Capsicum spp.) is one of the most economically important vegetables of Pakistan and it is grown throughout the country. It is a rich source of nutrition especially vitamins A, B, C and E along with minerals as folic acid, manganese (Mn), potassium (K) and molybdenum (Mo). Chilli possesses seven times more amount of vitamin C than an orange. Vitamin A, C and betacarotenoids are strong antioxidants to scavenge the free radicals. Chilli production is restricted due to various biotic factors. Among these viruses, Chilli veinal mottle virus (ChiVMV) is one of the most destructive and menacing agents that inflicts heavy and colossal losses that accounted for 50% yield loss both in quality and quantity. Pathogen-Derived Resistance (PDR) approach is considered one of the effective approaches to manage plant viruses. In this study, ChiVMV was characterized on a molecular level, the coat protein (CP) gene of the virus was stably transformed into Nicotiana benthamiana plants using Agrobacterium tumefaciens. The transgenic plants were challenged with the virus to evaluate the level of resistance of plants against the virus. It was observed that the plants expressing CP gene have partial resistance against the virus in terms of symptoms' development and virus accumulation. Translation of this technique into elite chilli varieties will be resulted to mitigate the ChiVMV in the crop as well as an economic benefit to the farmers.
Vegetais são uma importante fonte de renda e culturas de alto valor para os pequenos agricultores. A pimenta-malagueta (Capsicum spp.) é uma das hortaliças mais importantes economicamente do Paquistão e é cultivada em todo o país. É uma rica fonte de nutrição, especialmente vitaminas A, B, C e E com minerais como ácido fólico, manganês (Mn), potássio (K) e molibdênio (Mo). O pimentão possui sete vezes mais vitamina C do que a laranja. Vitaminas A e C e betacarotenoides são antioxidantes fortes para eliminar os radicais livres. A produção de pimenta é restrita devido a vários fatores bióticos. Entre esses vírus, o ChiVMV é o agente mais destrutivo e ameaçador que inflige perdas pesadas e colossais que representam 50% da perda de rendimento, tanto em qualidade quanto em quantidade. A abordagem de resistência derivada de patógenos (PDR) é considerada uma das abordagens eficazes para gerenciar os vírus de plantas. Neste estudo, ChiVMV foi caracterizado em nível molecular e o gene CP do vírus foi transformado de forma estável em plantas Nicotiana benthamiana usando Agrobacterium tumefaciens. As plantas transgênicas foram desafiadas com o vírus para avaliar seu nível de resistência contra o vírus. Observou-se que as plantas que expressam o gene CP apresentam resistência parcial ao vírus em termos de desenvolvimento de sintomas e acúmulo de vírus. A tradução dessa técnica em variedades de pimenta de elite resultará na mitigação do ChiVMV na safra, bem como em benefícios econômicos para os agricultores em termos de melhor rendimento e baixo custo de produção.

RESUMO
Background:The aim of this doubleblind prospective study was to determine whether administering 1 gm Tranexamic Acid (TXA) would the intraoperative blood loss during the Open Reduction and Internal Fixation (ORIF) surgery of mandibular fracture via the intraoral approach operated under local anesthesia (LA).Material And Methods:20 patients who underwent ORIF surgery ofmandibular fractures under LA were randomly allocated to two groups. Study group was administered 1 gm TXA diluted in a 500 ml Ringer Lactate solution one hour before thesurgery. Control group did not receive any such IV infusion. All the surgeries were performed by the same surgeon.Result:Mean difference in Intraoperative blood loss between the two groups was found out to be statistically insignificant. Effect of age, gender or site of fracture was also found out to be insignificant. Conclusion:There is not much effect of TXA on intraoperative blood loss during ORIF of a mandibular fracture via the intraoral approach. Even without tranexamic, if area is infiltrated with adrenaline, proper flap reflection and tissue handling technique is used, and vital structures avoided; blood loss will be minimal.
RESUMO
Background: India ranks among the bottom five countries in public health spending. Out of pocket spending of households on healthcare is almost 70% of income and reimbursement in any form availed by households whose members are employed in the formal sector is negligible. Objectives: To determine the usual source of medical care opted for by the study population. To find out the illness pattern and its age/sex distribution in the study population. To find out the expenditure incurred on illness and its source of procurement by the study population. Methodology: 52.42% urban Aligarh resides in slums. A cross sectional study was done to study the newer slum pockets. 3409 households with a population of 16,978 were studied with the help of pretested questionnaire; SPSS 20 was used for statistical analysis. Results: In our study, we found that almost all the households suffered from catastrophic health expenditure. The study population, which was already vulnerable owing to their low socio-economic and migrant status was further forced into poverty and indebtedness on account of expenditure on illness. Conclusions: National health financing systems should be designed to protect households from financial catastrophe, by reducing out-of-pocket spending.
RESUMO
Background: India needs around 2,77,000 donations annually to perform 1,00,000 corneal transplants. To enhance the procurement of corneal donations further, raising the level of public education on eye donation was the most important first step. The Govt. of India under the 11th 5-year plan envisages eliminating avoidable blindness completely by 2020. The aim and objective of the study was to compare the awareness of eye donation and willingness to donate eyes among medical and paramedical students.Methods: A cross sectional study was carried out among 400 final year MBBS students and interns and also among the final year B.Sc. nursing students and at Hi-Tech Medical College and Hospital, Bhubaneswar from August 2018 to September 2018.Results: The study participants were in the age group of 18-25 years. While 100% medical students had heard about organ donation, 85.5% of paramedical students heard about organ donation. Positive opinion regarding donation of eye post death was got from all the medical students as against 85% of paramedical students. More than 1/3rd of the study participants in both the groups were willing to donate eyes and know more regarding the same and also had a fair idea regarding shortage of donors in India.Conclusions: Awareness of eye donation is better in medical students compared to paramedical students, preferably due to the exposure and study curriculum. Most of the students in both groups were inclined to pledge for eye donation. Awareness regarding eye donation will form the prime base for the elimination of avoidable blindness in India.
RESUMO
Background: One of the most important public health issue for developing nations in the world with special reference to India is preventive blindness. In the world, 36 million people are blind and 217 million people are with moderate or severe distance vision impairment. The aim and objectives of the study were a qualitative survey to get an initial picture of rural residents knowledge of the prevalent eye disease; serve as an initial assessment of patient’s baseline knowledge of eye conditions and possible treatment methods to aid in the future development of educational outreach initiatives and studies.Methods: A cross sectional study was carried out in the rural areas of Jajpur, Nayagarh, Puri and Cuttack district of Odisha during preventive eye screening camps. The study was carried over 6 months from Jan to July 2018. The sample size was calculated to be 914 and the study subjects were all aged 40 years and above comprising of 64.7% male and 35.3% female.Results: In this study we found out that 60.18% reported previous eye doctor visits, 24.08% reported using eye drops prescribed by a non-doctor, while 60.18% of the non-doctor visitors reported not knowing that a doctor should prescribe eye drops. While 76.69% had little or no awareness regarding glaucoma, 51.87% had a fair idea regarding cataract surgery.Conclusions: The increase in patient awareness of prevalent eye diseases and treatments could lead to an increase in patient acceptance regarding the importance of routine eye examinations for proper identification and treatment of various eye conditions.
RESUMO
A 24-year-old male presented with a painless yellowish lesion on the nasal part of his cornea that extended to the paracentral area. Without a confirmed clinical diagnosis, the patient was advised surgical removal of the lesion. The lesion showed a smooth, elevated anterior surface without any signs of inflammation. On making a small incision over the lesion, we found yellowish material being extruded from the lesion. Cytological evaluation of the material revealed clear vacuolated cells suggestive of lipocytes, based on which we diagnosed it a rare case of corneal lipoma.
RESUMO
Purpose: Candida auris is a recently recognized yeast pathogen, which has attracted worldwide attention due to its multidrug-resistant nature and associated high mortality rates. Its persistence in hospital environment and propensity of nosocomial transmission underscores the need of continuous monitoring to prevent outbreaks. Since the first case of C. auris candidemia in May, 2014, we have identified 17 additional invasive cases, which are described here
Methods: Identity of 17 isolates originating from proven or possible cases of invasive C. auris infection and identified as Candida haemulonii by Vitek 2 yeast identification system was confirmed by PCR-sequencing of rDNA. Information about risk factors, treatment and outcomes were retrospectively retrieved from case files. Antifungal susceptibility testing was performed by Etest
Results: Thirteen cases of candidemia and 4 cases of other invasive infections were detected in 6 hospitals across Kuwait. Major risk factors included adult patients with cancer, diabetes, gastrointestinal/ liver diseases and extended [> 25 days] hospital stay. All isolates were resistant to fluconazole. Additionally, 5 and 4 isolates were also resistant to voriconazole and amphotericin B, respectively. Despite antifungal treatment, 9 of 15 patients died. Most patients [n = 12] were hospitalized in 2 hospitals that are in close proximity, whereas 5 other patients were from 3 hospitals that are situated > 10 km apart
Conclussion: Occurrence of successive cases of invasive C. auris infections with resulting mortality in nine patients suggests persistence of this multidrug-resistant yeast in major hospitals in Kuwait. Early detection by continuous surveillance and enforcement of infection control measures are recommended
RESUMO
Abstract Objective Candida albicans is the primary causative agent of oral candidosis, and one of its key virulent attributes is considered to be its ability to produce extracellular phospholipases that facilitate cellular invasion. Oral candidosis can be treated with polyenes, and azoles, and the more recently introduced echinocandins. However, once administered, the intraoral concentration of these drugs tend to be sub-therapeutic and rather transient due to factors such as the diluent effect of saliva and cleansing effect of the oral musculature. Hence, intra-orally, the pathogenic yeasts may undergo a brief exposure to antifungal drugs. We, therefore, evaluated the phospholipase production of oral C. albicans isolates following brief exposure to sub-therapeutic concentrations of the foregoing antifungals. Materials and methods Fifty C. albicans oral isolates obtained from smokers, diabetics, asthmatics using steroid inhalers, partial denture wearers and healthy individuals were exposed to sub-therapeutic concentrations of nystatin, amphotericin B, caspofungin, ketoconazole and fluconazole for one hour. Thereafter the drugs were removed and the phospholipase production was determined by a plate assay using an egg yolk-agar medium. Results The phospholipase production of these isolates was significantly suppressed with a percentage reduction of 10.65, 12.14, 11.45 and 6.40% following exposure to nystatin, amphotericin B, caspofungin and ketoconazole, respectively. This suppression was not significant following exposure to fluconazole. Conclusions Despite the sub-therapeutic, intra oral, bioavailability of polyenes, echinocandins and ketoconazole, they are likely to produce a persistent antifungal effect by suppressing phospholipase production, which is a key virulent attribute of this common pathogenic yeast.

Background- Hypertrophic cardiomyopathy (HCM) is a genetically transmitted disease with diverse natural history for which the potential to produce adverse consequences has been emphasized. However, the possibility of this disease remaining clinically dormant for many years has not been as widely appreciated. Certainly, the clinical recognition of previously undiagnosed patients with HCM may be advantageous by permitting risk stratification for sudden cardiac death or for timely pharmacologic therapy when symptoms intervene. The purpose of this study was to assess the disease pattern and the extent to which hypertrophic cardiomyopathy (HCM) exists undetected in a suspected group of population never diagnosed to have any cardiovascular disease, referred from the primary care facilities to one of the largest tertiary level hospital of Bangladesh. Methods-We prospectively conducted an echocardiographic survey in 3648 cases between 19-03-2009 to 03-08-2010 (18 months) in the cardiac centre of Combined Military Hospital, Dhaka, Bangladesh. Results- A total of 3648 cases referred by primary care physicians underwent echocardiogram either to confirm a new diagnosis or to exclude obvious cardiovascular abnormalities. Hypertrophic cardiomyopathy was identified in 148 patients (4.06%) who was not known have any cardiac disease before. At diagnosis, age ranged from 20 to 83 years (mean 52.19) with male gender preponderance (85.81%). Ninety eight patients (67%) had no functional limitation and the remaining fifty patients reported with symptoms mostly giving multiple responses like chest pain (39.2%), palpitation (18.9%), dyspnoea (22.3%), unusual fatigability (16.9%) and syncope (6.8%). Twelve patients had strong suspicion of familial predisposition depending on the symptomatology of the familial tree but were confirmed only in 03 cases by echocardiography. Basal left ventricular outflow obstruction (gradients 20 to 76 mm Hg) was evident in 14 patients (9.45%). Relatively variable phenotypic expression of the disease was substantiated by diffuse thickening of left ventricular wall occurring more commonly than localized distributed hypertrophy (56.08% vs. 43.94%, respectively). Electrocardiogram was abnormal in almost 95% of cases and typical pattern of left ventricular hypertrophy was observed in 25.68% cases. Conclusion -This prospectively assembled data show that HCM cases may remain asymptomatic, clinically dormant and undetectable for many years (often to advance ages) in our community. The actual prevalence of the disease in our community needs to be ascertained which might exceed the prevalence mentioned in the text books.
RESUMO
Invasive candidiasis is a life-threatening complication of critically ill immunocompromised patients with high attributable mortality. Due to non-specific clinical presentation, early detection of candidemia and accurate identification of Candida species are essential pre-requisites for improved therapeutic outcome. Since blood culture-based methods lack sensitivity and species-specific identification by conventional methods is time-consuming, detection of immunological and molecular markers has provided an alternative for early diagnosis of invasive candidiasis. Additionally, serial estimations of these biomarkers have provided opportunities to monitor response to therapy and initiate pre-emptive therapy in suspected patients before clinical signs appear. Antigen-based methods include detection of β-D-glucan, a panfungal marker, and Candida mannan, a genus-specific marker. Although both these markers have moderate sensitivity, they provide a useful adjunct to the diagnosis if performed in select patient population in parallel for exclusion of false positive/negative results. A negative β-D-glucan test on at least two occasions has a high negative predictive value. Concomitant detection of Candida mannan and anti-mannan antibodies has sensitivity of ~70% before blood cultures become positive. Significant advances have also been made in nucleic acid-based detection methods, including a commercial real-time PCR assay (SeptiFast) for detection of five major clinically important Candida spp. in blood specimens within 6 h. Furthermore, matrix-assisted laser desorption ionization time-of-flight mass spectrometry enables species-specific identification of yeast isolates within an hour. While these immunological and molecular tools mark a significant advance towards early and specific diagnosis of candidemia and invasive candidiasis, further evaluation of these approaches in different clinical settings is warranted.

Aim: Lipid profile and glycosylated hemoglobin level changes in gestational diabetes. The extent to which this alteration takes place is still not clearly documented. Materials and Methods: To add a clear answer to this question, lipid profile parameters, and glycosylated hemoglobin status were determined in patients with gestational diabetes mellitus and compared to healthy pregnant women (controls). Results: Fasting plasma glucose levels, plasma glucose levels 1 hour, and plasma glucose levels 2 hours after 75 gm oral glucose administration (oral glucose tolerance test) were significantly higher in patients with gestational diabetes as compared to controls. Glycosylated hemoglobin was significantly higher in gestational diabetes than in controls. It was observed that there was a significant increase in serum cholesterol and serum triglyceride level in cases with gestational diabetes when compared to healthy pregnant women. Conclusion: The results of our study suggest that abnormal glucose levels, glycosylated hemoglobin, serum cholesterol, and serum triglycerides play an important role in pathophysiology of gestational diabetes, and therefore, extensive studies are required. Early diagnosis of gestational diabetes will decrease adverse neonatal and maternal outcomes.
RESUMO
Drugs used locally or systemically induce several alterations in micro and macroscopic tissues. However, nearly 20 drugs have been reported so far in the literature associated with gingival enlargement. Many systemic diseases have limited therapeutic options and such drugs or their metabolites have an adverse influence on different systems/organs, and one of these is that they initiate or accelerate the overgrowth of gingival tissue. The increase in size may be to the extent that teeth may be partially or completely covered, and the resultant 'gummy smile' may result in aesthetic concern for the patient.In the presence of bacterial inflammation in the gingiva, many of these drugs enhance the production of collagen by fibroblast cells, and simultaneously retard the destruction of collagen and hence increase the bulk of gingival tissue. It is apparent that there is a subpopulation of fibroblasts which is sensitive to these drugs. The exuberant growth of gingival tissue is of great aesthetic concern, which may require mechanical removal of bacterial plaque, calculus, and surgical intervention, and/or substitution of the drug with analogs. A relatively healthy oral environment provided by the dentist will reduce local microflora that will help in eliminating the major focus of infection. Physicians, general practitioners, and dentists need to make a coordinated and concise treatment plan that will be beneficial for the patients. This article will facilitate full information to physicians to involve dentists in the multidisciplinary treatment plan.

Background: Conventional coronary artery bypass surgery (CABG) is associated with substantial morbidity caused by cardiopulmonary bypass (CPB) and median sternotomy. Here we described an innovative technique to perform complete revascularization through a left lateral thoracotomy without CPB (ThoraCAB). Methods: From September 2005 to December 2008 a total 83 patients underwent ThoraCAB in National Institute of Cardio Vascular Diseases (NICVD). The patient is positioned with the left side elevated to 45 degree. A 6 to 8 inches long incision is made over the left 4th or 5th intercostal space from just medial to the nipple to the anterior axillary line. The left internal mammary artery (LIMA) is harvested as a pedicle graft under vision. Distal coronary anastomosis is completed first on the beating heart using a stabilizer, followed by proximal anastomoses on the descending aorta. Peroperative and postoperative complication the arrhythmia hypotension wound infection death was observed. Results: Complete revascularization was achieved in all patients. The number of grafts averaged 2.18±1.08 per patients. One patient died (1.2%) due to severe respiratory acidosis. One patient (1.2%) was converted to CPB due to arrhythmia. No strokes were observed. Of these patients, 7.2% developed new onset postoperative atrial fibrillation. Conclusion: ThoraCAB has been feasible in the vast majority of the patients requiring CABG surgery. The prevalence of the post operative atrial fibrillation was low. Left lateral thoracotomy offers an attractive and effective alteration to Off Pump median sternotomy.
