ABSTRACT
Abstract Smog has become the fifth season of Pakistan especially in Lahore city. Increased level of air pollutants (primary and secondary) are thought to be responsible for the formation of smog in Lahore. Therefore, the current study was carried out for the evaluation of air pollutants (primary and secondary) of smog in Wagah border particularly and other sites (Jail road, Gulburg) Lahore. For this purpose, baseline data on winter smog from March to December on primary and secondary air pollutants and meteorological parameters was collected from Environmental Protection Department and Pakistan Meteorological Department respectively. Devices being used in both departments for analysis of parameters were also studied. Collected data was further statistically analyzed to determine the correlation of parameters with meteorological conditions and was subjected to air quality index. According to results, PM 10 and PM 2.5 were found very high above the NEQS. NOx concentrations were also high above the permissible limits whereas SO2 and O3 were found below the NEQS thus have no roles in smog formation. Air Quality Index (AQI) of pollutants was PM 2.5(86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) and SO2 (10-95). AQI of PM 2.5 remained between moderate to very unhealthy levels. AQI of PM 10 remained between good to hazardous levels. AQI of NOx remained between good to unhealthy for sensitive groups levels. AQI of O3 and SO2 remained between good to moderate levels. Pearson correlation showed that every pollutant has a different relation with different or same parameters in different areas. It is concluded from the present study that particulate matter was much more responsible for smog formation. Although NOx also played role in smog formation. So there is need to reduce sources of particulate matter and NOx specifically in order to reduce smog formation in Lahore.
Resumo Smog tornou-se a quinta estação do Paquistão, especialmente na cidade de Lahore. Acredita-se que o aumento do nível de poluentes atmosféricos (primários e secundários) seja responsável pela formação de poluição atmosférica em Lahore. Portanto, o presente estudo foi realizado para a avaliação dos poluentes atmosféricos (primários e secundários) do smog na fronteira de Wagah em particular e em outros locais (Jail road, Gulburg) Lahore. Para este propósito, os dados de referência sobre a poluição atmosférica de inverno de março a dezembro sobre poluentes atmosféricos primários e secundários e parâmetros meteorológicos foram coletados do Departamento de Proteção Ambiental e do Departamento Meteorológico do Paquistão, respectivamente. Dispositivos sendo usados em ambos os departamentos para análise de parâmetros também foram estudados. Os dados coletados foram posteriormente analisados estatisticamente para determinar a correlação dos parâmetros com as condições meteorológicas e foram submetidos ao índice de qualidade do ar. De acordo com os resultados, PM 10 e PM 2,5 foram encontrados muito acima do NEQS. As concentrações de NOx também estavam muito acima dos limites permitidos, enquanto SO2 e O3 foram encontrados abaixo do NEQS, portanto, não têm papéis na formação de smog. O índice de qualidade do ar (AQI) de poluentes foi PM 2,5 (86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) e SO2 (10-95). O AQI de PM 2,5 permaneceu entre níveis moderados a muito prejudiciais à saúde. O AQI de PM 10 permaneceu entre níveis bons e perigosos. AQI de NOx permaneceu entre bom e não saudável para os níveis de grupos sensíveis. O AQI de O3 e SO2 permaneceu entre níveis bons a moderados. A correlação de Pearson mostrou que cada poluente tem uma relação diferente com parâmetros diferentes ou iguais em áreas diferentes. Conclui-se do presente estudo que o material particulado foi muito mais responsável pela formação de smog. Embora o NOx também tenha desempenhado um papel na formação do smog. Portanto, é necessário reduzir as fontes de partículas e NOx, especificamente para reduzir a formação de smog em Lahore.

For beginner surgeons, it is difficult to recognize the posterior capsule during cataract surgery. In the case of brown cataracts with a thin posterior capsule and in cataracts with asteroid hyalosis, it is difficult to identify the capsule before intraocular lens (IOL) implantation even for expert surgeons. Here we illustrate five important signs, which can be practiced in routine cases to make sure the posterior capsule is intact, before IOL implantation.
ABSTRACT
Dengue fever vectored by the mosquito Aedes aegypti is one of the most rapidly spreading insect-borne diseases. Current reliance of dengue vector control is mostly on chemical insecticides. Growing insecticide resistance in the primary mosquito vector, Aedes aegypti, limits the effectiveness of vector control through chemical insecticides. These chemical insecticides also have negative environmental impacts on animals, plants and human health. Myco-biocontrol agents are naturally occurring organisms and are found to be less damaging to the environment as compared to chemical insecticides. In the present study, entomopathogenic potential of local strains of fungi isolated from soil was assessed for the control of dengue vector. Local fungal isolates presents better alternative to introducing a foreign biocontrol strain, as they may be better adapted to environmental conditions of the area to survive and may have more entomopathogenic efficacy against target organism. Larvicidal efficacy of Fusarium equiseti and Fusarium proliferatum was evaluated against Aedes aegypti. Local strains of F. equiseti (MK371718) and F. proliferatum (MK371715) were isolated from the soil of Changa Manga Forest, Pakistan by using insect bait method. Larvicidal activity of two Fusarium spp. was tested against forth instar larvae of A. aegypti in the laboratory, using concentrations 105, 106, 107 and 108 conidia /ml. LC50 values for F. equiseti after 24h, 48h, 72h and 96h of exposure were recorded as 3.8x108, 2.9x107, 2.0x107, and 7.1x106 conidia /ml respectively while LC50 values for F. proliferatum were recorded as 1.21x108, 9.6x107, 4.2x107, 2.6x107 conidia /ml respectively after 24h, 48h, 72h and 96h of exposure. The results indicate that among two fungal strains F. equiseti was found to be more effective in terms of its larvicidal activity than F. proliferatum against larvae of A. aegypti.

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
ABSTRACT
@# Corona virus SARS-CoV-2-induced viral disease (COVID-19) is a zoonotic disease that was initially transmitted from animals to humans. The virus surfaced towards the end of December 2019 in Wuhan, China where earlier SARS (Severe Acute Respiratory Syndrome) had also surfaced in 2003. Unlike SARS, SARS-CoV-2 (a close relative of the SARS virus) created a pandemic, and as of February 24 2021, caused 112,778,672 infections and 2,499,252 deaths world-wide. Despite the best efforts of scientists, no drugs against COVID-19 are yet in sight; five vaccines have received emergency approval in various countries, but it would be a difficult task to vaccinate twice the world population of 8 billion. The objective of the present study was to evaluate through in silico screening a number of phytochemicals in Allium cepa (onion) regarding their ability to bind to the main protease of COVID-19 known as the 3C-like protease or 3CLpro, (PDB ID: 6LU7), 3CLpro of SARS (PDB ID: 3M3V), and human angiotensin converting enzyme-2 (ACE-2), [PDB ID: 1R42], which functions as a receptor for entry of the virus into humans. Molecular docking (blind docking, that is docking not only against any target pocket) were done with the help of AutoDockVina. It was observed that of the twenty-two phytochemicals screened, twelve showed good binding affinities to the main protease of SARS-CoV-2. Surprisingly, the compounds also demonstrated good binding affinities to ACE-2. It is therefore very likely that the binding affinities shown by these compounds against both 3CLpro and ACE-2 merit further study for their potential use as therapeutic agents.
ABSTRACT
OBJECTIVE@#This study was undertaken to investigate the antihyperglycemic potential of miracle fruit (MF) as well as its hepatic safety as compared to aspartame in alloxan-induced diabetic mice.@*METHODS@#MF extracts were prepared and screened for their phytochemical composition using high-performance liquid chromatography (HPLC). Total phenolic, flavonoid and tannin contents and antioxidant potential were also determined. Additionally, MF was evaluated for its sensory attributes. For in vivo work, MF ethanol extract at high (MFH: 500 mg/kg body weight [BW]) and low (MFL: 250 mg/kg BW) doses as well as aspartame were injected intraperitoneally into alloxan-induced diabetic mice. Blood glucose levels were determined following acute and subchronic treatment. At the end of the study, animals were sacrificed, serum was collected for biochemical analysis and liver tissues were obtained for histopathological examination.@*RESULTS@#MF ethanol extract contained more flavonoids and tannins, and had higher 1,1-diphenyl-1-picrylhydrazyl radical-scavenging activity (79.61%) compared to MF aqueous extract (P < 0.05). HPLC analysis of MF ethanol extract also revealed the presence of 10 antioxidants with quercetin comprising the major polyphenol. Additionally, sensory analysis of MF showed that its intake is effective in masking undesirable sourness. Subchronic administration of MFH proved amelioration of hyperglycemia in mice as compared to aspartame. Moreover, aspartame treatment significantly elevated (P < 0.05) the level of alanine aminotransferase and had destructive effects on the liver histopathology; however, hepatic architecture was restored by low and high doses of MF.@*CONCLUSION@#MF is an effective antihyperglycemic with hepatoprotective properties that can be used as a healthier alternative sweetening agent in place of aspartame for sour beverages.
ABSTRACT
@#Cystic Echinococcosis (CE) is one of the most important zoonotic parasitic diseases in human, livestock, and wildlife globally. The prevalence of CE depends upon human behavioral risk factors, the diversity and ecology of animal host interactions and the genetic diversity within Echinococcus species which differ in their zoonotic potential and pathogenicity. It is a neglected, economic and socio-cultural problem in Pakistan. The available data about the incidence of CE is very limited and no extensive study has been reported in Pakistan. The current study was aimed to analyze the hospital reported cases of CE and the associated risk factors related to the incidence of CE. The hospital-based data of CE for the time period of January 2012-December 2017 was collected from Islamabad, Rawalpindi and Peshawar. The data covered demographic characteristics including age, gender, and cyst localization of infected individuals and socioeconomic determinants. The data was analyzed based upon different risk factors along with the different socioeconomic parameters that has an important impact on the distribution of disease. A total of 228 cases were presented in the selected hospitals of different cities during the study period. Out of total 228 patients, 59.21% were males and 40.78% were females (P<0.001). Most infections have been recorded in young adults (>20-30) showing 22.8% of total infected individuals followed by children (0-10) showing 10.5% (n=24), respectively (P<0.001). Liver was the most vulnerable organ (58.77%, n=134) followed by lungs (14.47%, n=33) (P<0.001). The infection was higher among rural communities (84.2%) than urban (12.8%) (P<0.001). Socioeconomic and demographic factors had an important impact on the intensity of disease (P<0.001). The occurrence of cases in children and young adults was an important finding as it indicated an active transmission of the parasite in Pakistan along with the poverty index. Emergence of echinococcosis in Pakistan showed that emerging health issues in Pakistan could bring the disease to limelight for future research. This finding, together with the fact that 1 hospital reported 214 cases over 6 years 325 underlines the need for a program for prevention/control of this disease in Pakistan. The timely measure needs to be taken to hamper the disease development and establishment. In order to control the disease, complete surveillance should be done which in turn weighs down the disease progress.
ABSTRACT
OBJECTIVE@#An extract of Costus speciosus (CSE), a herb widely used in folk medicine, was evaluated for its antioxidant, antihyperlipidemic and ameliorating effects on histopathological changes in atherogenic rabbits.@*METHODS@#Twenty-four male rabbits (Oryctolagus cuniculus) were divided into 4 groups. Three groups were fed a diet containing 3% saturated fat and 1.3% cholesterol for 40 d. One of these was sacrificed on the 40th day and was called the pathogenic (P) group; the other two groups received treatment for another 30 d as follows: one received 0.8 g/(kg·d) of CSE and the other was given 0.01 g/(kg·d) of simvastatin. The normal group was sacrificed on the 70th day and used as a control.@*RESULTS@#CSE showed radical-scavenging ability. Administration of CSE for a 30-day period resulted in a significant decrease in total cholesterol, triacylglycerol, low-density lipoprotein and aspartate aminotransferase compared to the P group, while levels of hemoglobin, packed corpuscular volume and red blood cells were elevated. With respect to studies performed on the heart, a decrease in malondialdehyde and an increase in reduced glutathione were noted. Total protein increased in the liver, heart and aorta after treatment with CSE and also a marked improvement in histopathological parameters was demonstrated.@*CONCLUSION@#The present findings indicate that the C. speciosus rhizome possesses antiatherogenic and antioxidant properties which may provide protective effects against oxidative stress in atherosclerotic rabbits.
ABSTRACT
@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> In view of renewed interest in primary health care (PHC) as a framework for health system development, there is a need to revisit how successful community health programs implemented the PHC approach, and what factors should be considered to scale up its implementation in order to sustainably attain ideal community health outcomes in the Philippines.</p><p style="text-align: justify;"><strong>OBJECTIVE AND METHODOLOGY:</strong> Using the 2008 World Health Report PHC reform categories as analytical framework, this systematic review aimed to glean lessons from experiences in implementing PHC that may help improve the functioning of the current decentralized community-level health system in the country, by analyzing gathered evidence on how primary health care evolved in the country and how community health programs in the Philippines were shaped by the PHC approach.</p><p style="text-align: justify;"><b>RESULTS:</b> Nineteen (19) articles were gathered, 15 of which documented service delivery reforms, two (2) on universal coverage reforms, three (3) on leadership reform, and one (1) on public policy. The literature described how successful PHC efforts centered on community participation and empowerment, thus pinpointing how community empowerment still needs to be included in national public health thrusts, amid the current emphasis on performance indicators to evaluate the success of health programs.</p><p style="text-align: justify;"><strong>CONCLUSION AND RECOMMENDATIONS:</strong> The studies included in the review emphasize the need for national level public health interventions to be targeted to community health and social determinants of health as well as individual health. Metrics for community empowerment should be developed and implemented by government towards sustainable health and development, while ensuring scientific validity of community health interventions.</p>

Collection of real-time, standardized data remains a challenge for public health surveillance systems. The use of mobile information technology may facilitate this. A national case-based public health surveillance system was introduced in Jordan in 2015 using mobile tablets and an online framework. After training on the system, users were surveyed about their perceptions of it. Of 596 participants attending the training, 580 [97.3%] completed the survey. The majority of users were nurses [58.5%]. Overall perceptions of the system were highly positive across 5 areas of functionality [standardized case definitions, clinical guidance on signs and symptoms, risk factors and laboratory guidance, SMS and Email alerts for notifiable diseases, one-hour reporting of information via an online framework]. In all areas, over 80% of participants thought the system would help their work and would save time in identifying notifiable diseases and reporting this information centrally. Further work is encouraged to evaluate the system and consider the application of cloud-based models in other settings

ABSTRACT Objective: To determine the responsiveness of the domain climbing up and going down stairs of the Functional Evaluation Scale for Duchenne Muscular Dystrophy (FES-DMD-D3) in a one-year follow-up study. Method: The study included 26 patients with DMD. Effect Size (ES) and Standardized Response Mean (SRM) described the scale’s responsiveness. Results: For climbing up stairs, ES showed that responsiveness was low in the three-month assessments (0.26; 0.35; 0.13; 0.17), low to moderate in the six-month assessments (0.58; 0.48; 0.33), moderate in the nine-month assessments (0.70; 0.68), and high in the 12-month assessment (0.88). SRM showed that responsiveness was low in the three-month assessments (0.29; 0.38; 0.18; and 0.19), low to moderate in the six-month assessments (0.59; 0.51; 0.36), moderate in the nine-month assessments (0.74 and 0.70), and high in the 12-month assessment (0.89). For going down stairs, ES showed that responsiveness was low in the three- and six-month assessments (0.16; 0.25; 0.09; 0.08 and 0.48; 0.35; 0.18, respectively), low to moderate in the nine-month assessments (0.59; 0.44), and moderate in the 12-month assessment (0.71). SRM showed that responsiveness was low in the three- and six-month assessments (0.25; 0.35; 0.12; 0.09 and 0.47; 0.38; 0.21, respectively), low to moderate in the nine-month assessment (0.62; 0.49), and moderate in the 12-month assessment (0.74). Conclusion: Climbing up stairs should be assessed at intervals of nine months or longer, when responsiveness is moderate to high. Going down stairs should be assessed annually because moderate responsiveness was observed in this period.

ABSTRACT Measuring muscle strength and motor function is part of Duchenne muscular dystrophy (DMD) assessment. However, the relationship between these variables is controversial. Objective To investigate the relationship between muscle strength and motor function and between these variables and age. Method Muscle strength was measured by Medical Research Council (MRC) scale and motor function, by Motor Function Measure (MFM), in 40 non-ambulatory patients. Spearman tests investigated the relationships between muscle strength, motor function and age. Results Total MRC and MFM scores were strongly related to each other (r = 0.94; p < 0.001), but not to age (r = -0.19, r = -0.31, respectively; p > 0.05). Strong and moderate relationships between partial muscle strength and motor function scores were found. Higher correlation coefficients were found between total scores and Dimensions 2 (axial/ proximal control) and 3 (distal control) of MFM. Conclusion Muscle strength and motor function are strongly correlated and seem to decrease proportionally in DMD.
RESUMO Mensurar força muscular e função motora é parte da avaliação em distrofia muscular de Duchenne (DMD). A relação entre essas variáveis é controversa. Objetivo Investigar a relação entre força muscular, função motora e idade. Método Força muscular foi medida pela Medical Research Council (MRC), e função motora pela escala Medida da Função Motora (MFM), em 40 pacientes cadeirantes. Teste de Spearman investigou as relações entre força muscular, função motora e idade. Resultados O escore total da escala MRC e da MFM foram fortemente relacionados entre si (r = 0,94; p < 0,001), mas não com a idade (r = -0,19; r = -0,31, respectivamente; p > 0,05). Foram encontradas correlações fortes e moderadas entre os escores parciais de força muscular e função motora. As relações mais fortes ocorreram entre os escores totais, Dimensão 2 (controle axial/proximal) e 3 (controle distal) da escala MFM. Conclusão Força muscular e função motora estão fortemente correlacionadas e parecem diminuir proporcionalmente na DMD.

Cholesteatoma is a disease of the middle ear characterized by the presence of squamous epithelium in the middle earcleft. By secreting chemical enzymes, it causes manifestations by bone erosion which is dangerous to the surrounding structures which are intracranial and extra cranial. Due to advent of antibiotics and early diagnosis of ear disease, cholesteatoma is becoming infrequent. Previously commonly seen complications of cholesteatoma like mastoid abscess, automastoidectomy and sigmoid sinus abscess and granulations are rarely seen nowadays.A retrospective study ofcases of ear discharge with cholesteatoma presented to Government Medical College/Government General Hospital, Nizamabad, Telangana, during the period of May 2013 to June 2015 was done. The experience was being presented in this study.42 cases of cholesteatoma presenting with these features we re recorded. Chronicity of the disease with varied presentations seen rarely and the prevalence of the disease in poor socioeconomic families who had no access to medical facilities and ignorance of the severity of the disease is the main factor for seeing the rare presentations not seen in other centres. Inaccessibility to medical facilities and lack of expert treatment was the reason for patients seeking medical attention with conditions due to chronicity which are rarely seen nowadays.
ABSTRACT
Background: Blood transfusion is a life-saving therapeutic intervention and millions of lives are saved each year globally through this procedure. However, blood transfusions are associated with certain risks which can lead to adverse consequences. It may cause acute or delayed complications and carries the risk of the transmission of blood borne infectious agents. Materials and methods: This study was done in Government general hospital blood bank, Nizamabad district, Telangana state, India. Study duration was six years, from June 2010 to May 2016. Blood was collected from apparently healthy donors after following the questionnaire put forth by National AIDS Control Organization (NACO) through blood camps organized by voluntary organizations, voluntary and replacement donors in the government blood bank and motivated student bodies. Results: In our study, total screening positives were 532 out of the total 55291 units accounting to 0.96%. Among the positives, most of the positives belonged to Hepatitis B virus, HBsAg positives were 384 cases (0.69%), Human Immunodeficiency Virus (HIV) were 117 cases (0.20%), Venereal Ather Fatima, Farida Begum, Kandukuri Mahesh Kumar. Seroprevalence of Transfusion Transmissible Infections among Blood Donors in Nizamabad District of Telangana State - A six years study. IAIM, 2016; 3(8): 73-78. Page 74 Disease Research Laboratory test (VDRL) positives were 22 cases (0.03%) and minimal positives were noted in Hepatitis C virus (HCV) those were 09 cases (0.01%). Conclusion: Transfusion of blood and blood products is an established mode of treatment in many conditions. However unnecessary transfusions and unsafe transfusion practices expose patients to the risk of serious adverse transfusion reactions and transfusion-transmitted infections. This risk can be minimized by encouraging voluntary non-remunerative donation and screening of blood for TTI before transfusion with better screening methods like Enzyme Linked Immuno-sorbent Assay (ELISA), Nucleic Acid Amplification technique (NAT).
ABSTRACT
Osteoactivin is a heavily glycosylated protein shown to have a role in bone remodeling. Previous studies from our lab have shown that mutation in Osteoactivin enhances osteoclast differentiation but inhibits their function. To date, a classical receptor and a signaling pathway for Osteoactivin-mediated osteoclast inhibition has not yet been characterized. In this study, we examined the role of Osteoactivin treatment on osteoclastogenesis using bone marrow-derived osteoclast progenitor cells and identify a signaling pathway relating to Osteoactivin function. We reveal that recombinant Osteoactivin treatment inhibited osteoclast differentiation in a dose-dependent manner shown by qPCR, TRAP staining, activity and count. Using several approaches, we show that Osteoactivin binds CD44 in osteoclasts. Furthermore, recombinant Osteoactivin treatment inhibited ERK phosphorylation in a CD44-dependent manner. Finally, we examined the role of Osteoactivin on receptor activator of nuclear factor-κ B ligand (RANKL)-induced osteolysis in vivo. Our data indicate that recombinant Osteoactivin inhibits RANKL-induced osteolysis in vivo and this effect is CD44-dependent. Overall, our data indicate that Osteoactivin is a negative regulator of osteoclastogenesis in vitro and in vivo and that this process is regulated through CD44 and ERK activation.
