Objective: To elucidate the pattern of inheritance and determine the relative magnitude of various genetic effects for maturity and flowering attributes in subtropical maize. Methods:Four white grain maize inbred lines from flint group of corn, two with late maturity and two with early maturity, were used. These contrasting inbred lines were crossed to form four crosses. Six generations (P1, P2, F1, F2, BC1, and BC2) were developed for each individual cross. These were evaluated in triplicate trial for two consecutive years. Results: Both dominance gene action and epistatic interaction played major role in governing inheritance of days to pollen shedding, 50% silking, anthesis silking interval and maturity. Conclusions: Preponderance of dominance gene action for these traits indicated their usefulness in hybrid programs of subtropical maize.

Nosocomial infections or healthcare associated infections occur in patients under medical care.These infections occur worldwide both in developed and developing countries.Nosocomial infections accounts for 7％ in developed and 10％ in developing countries,As these infections occur during hospital stay,they cause prolonged stay,disability,and economic burden.Frequently prevalent infections include central line-associated bloodstream infections,catheter-associated urinary tract infections,surgical site infections and ventilator-associated pneumonia.Nosocomial pathogens include bacteria,viruses and fungal parasites.According to WHO estimates,approximately 15％ of all hospitalized patients suffer from these infections.During hospitalization,patient is exposed to pathogens through different sources environment,healthcare staff,and other infected patients.Transmission of these infections should be restricted for prevention.Hospital waste serves as potential source of pathogens and about 20％-25％ of hospital waste is termed as hazardous.Nosocomial infections can be controlled by practicing infection control programs,keep check on antimicrobial use and its resistance,adopting antibiotic control policy.Efficient surveillance system can play its part at national and international level.Efforts are required by all stakeholders to prevent and control nosocomial infections.

Objective: To isolate the entomopathogenic fungus Metarhizium anisopliae (M. anisopliae) in the local environment, and evaluate its efficacy against the suspected dengue vector Aedes albopictus in Pakistan. Methods: According to the standard procedure, M. anisopliae was isolated from the dead mosquitoes which were collected from the field or dead after the collection. Bioassay was performed to determine its efficacy. Results: The results indicated that M. anisopliae had larvicidal effect with LC50 value 1.09×105 and LC90 value 1.90×1013 while it took 45.41 h to kill 50%of tested population. Conclusions: Taking long time to kill 50% population when compare with the synthetic insecticides, is the only drawback for the use of entomopathogenic fungus but these bio-pesticides are safe for the use.

Networks of synaptically connected neurons underlie all brain functions. Various cell-cell signaling and extrinsic molecules influence synapse assembly at the synaptic site. Calcium ions play a significant role in signal transduction pathways that control various neuronal functions. Multifunctional Ca2+/calmodulin-dependent protein kinase II (CaMK II) is an important mediator of calcium signaling in neurons, it plays an essential role in controlling synaptic strength and plasticity, and it is highly expressed in the cytosol of developing neurons, especially in presynaptic neurons. However, the precise role of CaMKII in synapse formation and synaptic transmission has not yet been determined. We hypothesized that CaMKII activity could be necessary for synapse formation and synaptic transmission. To test whether CaMKII activity is required for the synapse formation and synaptic transmission, the identified neurons visceral dorsal 4 (VD4 – presynaptic) and its postsynaptic partner left pedal dorsal 1 (LPeD1) from the freshwater snail Lymnaea stagnalis were paired in soma-soma configuration in cell culture. The soma-soma paired cells recapitulated their excitatory connections in vitro. To test the possible role of CaMKII in synapse formation and synaptic transmission, the in vitro paired neurons were exposed to a CaMKII-specific inhibitor KN-93 and its inactive analog KN-92. The incidence of synapse formation and efficacy of synaptic transmission was tested electrophysiologically.

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan, and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.

A kinetic assay for total calcium in serum was developed which is based on the activation of Ca++-ATPase by free Ca++ [Ca++]f maintained by EGTA in the reaction mixture. The concentration of Caf++ was dependent on total reference calcium added or serum calcium. Ca++-ATPase activity was coupled to the reduction of NADH by pyruvate kinase (PK) and lactate dehydrogenase (LDH) and monitored by change in absorbance at 340 nm. The calcium in normal serum was 10.08 +/- 0.24 mg/ dl (n = 35) by our method while with o-cresolphthalein complexone (CPC) method, the total calcium in the same 35 serum samples was 10.14 +/- 0.54 mg/dl. The range of within-run coefficient of variations (CVs) by this method was 0.9-2.87% at 8-12 mg/dl and day-to-day CVs were 0.72-3.17%. The presence of other ions and standard clinical interfering agents did not affect this assay system. The correlation between values obtained with our method (y) and CPC method (x) for normal serum was: y = 1.064x-0.580 mg/dl (r = 0.912, n = 59).

Objective: To determine antiacanthamoebic activity of natural and marketed honey samples.
Methods: Natural honey samples were collected directly from the bee hive and marketed honey samples were purchased from the local market in Karachi, Pakistan. Both honey samples were tested for their flavonoid content (quercetin equivalent per gram of the extract) and phenolic content (gallic acid equivalent per gram). Furthermore, their anti-oxidant activity was determined by measuring 2,2-diphenyl-1-picrylhydrazyl. Using amoebistatic and amoebicidal assays, the effects of honey samples were tested against growth and viability of Acanthamoeba parasites.
Results: Natural honey exhibited potent amoebistatic and amoebicidal effects, in a concentration-dependent manner. Honey-treated Acanthamoeba castellanii showed loss of acanthopodia, following which amoebae detached, rounded up, reduced in size, decreased in cytoplasmic mass and they were observed floating in the culture medium. Importantly, honey-treated amoebae did not revive when inoculated in fresh growth medium, however, glycerol-treated amoebae exhibited viable trophozoite and active growth. In contrast, marketed honey samples varied in their efficacy against Acantha-moeba castellanii. The proportion of flavonoid, as determined by quercetin measurements and the proportion of phenolic, as determined by gallic acid measurements was higher in natural honey compared with marketed honey. Similarly, the antioxidant activity, as determined by 2,2-diphenyl-1-picrylhydrazyl scavenging activity was higher in natural honey vs. marketed honey.
Conclusions: This study shows that natural honey has antiacanthamoebic properties and possesses higher flavonoid, phenolic and antioxidant properties compared with the marketed honey. These findings are of concern to the public, health officials, and to the manufacturers regarding production of honey for medical applications.

Ramsay Hunt syndrome, also known as herpes zoster oticus is usually caused by reactivation of preexisting varicella zoster virus in the geniculate ganglion. Here we report a case of herpes zoster oticus masquerading as lateral pontomedullary syndrome occurring during the pre-eruptive phase of chicken pox. The case is being reported for its rare and unusual clinical presentation.

Purpose: Limited data exist regarding outcome and morbidity associated with portosystemic shunts in the pediatric transplant population. Our study assesses the outcomes of pediatric patients who underwent a portosystemic shunt procedure, both with and without liver transplantation (LT). Methods: This study retrospectively reviewed the medical records of pediatric patients aged 0–19 years who underwent shunt placement between 2003 and 2017 at a tertiary care center.The analysis included cases of shunt placement with or without LT. Results: A total of 13 pediatric patients were included in the study with median age of 8.8 years. Among the cases, 11 out of 13 (84.6%) underwent splenorenal shunt, 1 (7.7%) underwent a mesocaval shunt, and another 1 (7.7%) underwent a Modified Rex (mesoportal) shunt. Additionally, 5 out of 13 (38.5%) patients had LT, with 4 out of 5 (80.0%) receiving the transplant before shunt placement, and 1 out of 5 (20.0%) receiving it after shunt placement.Gastrointestinal bleeding resulting from portal hypertension was the indication in all cases.A total of 10 complications were reported in 5 patients; the most common complication was anemia in 3 (23.1%) patients. At the most recent follow-up visit, the shunts were functional without encephalopathy, and no deaths were reported. Conclusion Shunt placement plays a crucial role in the management of patients with portal hypertension. Our study demonstrates favorable long-term outcomes in pediatric patients who underwent shunt placement. Long term shunt outcomes were similar and unremarkable in patients with LT and without LT.

Albumin is the most abundant protein in human serum. A dye-binding method is commonly used in clinical laboratories for its estimation using different types of dyes. However, all these dye methods were interfered by a variety of compounds. Here we present a method for the detection of albumin in human serum and other biological fluids. The principle is based on the fact that lactate dehydrogenase isoenzyme-5 (LDH-5) binds specifically to Dextran-Blue (DB). Albumin inhibits the binding of LDH-5 with DB. Absence of LDH activity in DB fraction after gel filtration indicates the presence of albumin in sample and vice versa.
