DUSP4, an inducible protein has a substrate specificity toward ERK1/2, a component of MAP kinase which is enhanced during Leishmania infection. The DUSP4(-/-) mice show increased susceptibility towards the infection caused by Toxoplasma gondii and Leishmania mexicana. These observations emphatically established the fact that unlike DUSP1, DUSP4 has host protective role. In our study, it has been Leishmania donovani, the causative agent of visceral leishmaniasis (VL) significantly reduced the expression of DUSP4 during infection...

The scientific basis for antenatal corticosteroids (ACS) for women at risk of preterm birth has rapidly changed in recent years. Two landmark trials-the Antenatal Corticosteroid Trial and the Antenatal Late Preterm Steroids Trial-have challenged the long-held assumptions on the comparative health benefits and harms regarding the use of ACS for preterm birth across all levels of care and contexts, including resource-limited settings. Researchers, clinicians, programme managers, policymakers and donors working in low-income and middle-income countries now face challenging questions of whether, where and how ACS can be used to optimise outcomes for both women and preterm newborns...

Background The preferred timing of umbilical-cord clamping in preterm infants is unclear. Methods We randomly assigned fetuses from women who were expected to deliver before 30 weeks of gestation to either immediate clamping of the umbilical cord (≤10 seconds after delivery) or delayed clamping (≥60 seconds after delivery). The primary composite outcome was death or major morbidity (defined as severe brain injury on postnatal ultrasonography, severe retinopathy of prematurity, necrotizing enterocolitis, or late-onset sepsis) by 36 weeks of postmenstrual age...

INTRODUCTION: Low physical capability predicts mortality, perhaps by association with co-morbidity. However, few studies include participants <70years old with lower co-morbidity burdens compared to older adults. We examined relationships between usual walking speed (UWS), timed chair stands speed, grip strength, standing balance and all-cause mortality in 8477 participants aged 48-92years enrolled in the European Prospective Investigation of Cancer-Norfolk study. METHODS: Participants (55...

OBJECTIVES: Small for gestational age (SGA) infants are more susceptible to infectious morbidity and growth faltering compared to their appropriate for gestational age (AGA) counterparts. Zinc supplementation of SGA infants may be beneficial but the underlying susceptibility to zinc deficiency of SGA infants has not been examined. METHODS: In a community-based, observational, longitudinal study in a peri-urban settlement of Karachi, Pakistan, we compared the size of the exchangeable zinc pools (EZP) in term SGA and AGA infants at birth and at 6 months of age, hypothesizing that the EZP would be lower in the SGA group...

True and psychogenic nonepileptic seizures (PNES) go hand in hand. One colors the picture of other. Although it is thought that children carry lower risk for PNES than adults, this may represent the under-diagnosis of this condition in childhood due to few studies on this specific topic. Again, true seizure can be misdiagnosed by dramatic and varied manifestations appearing as psychological phenomena. We report a case of a 9-year-old boy presenting with sudden onset, short lasting, off and on different "melodramatic" episodic behavioral problems with La-Belle' indifference without loss of consciousness, appearing to be of psychogenic origin but finally ended with a diagnosis of temporal lobe epilepsy and responded dramatically with antiepileptics...

BACKGROUND: Although the effectiveness of community mobilisation and promotive care delivered by community health workers in reducing perinatal and neonatal mortality is well established, evidence in support of home-based neonatal resuscitation and infection management is mixed. We assessed the effectiveness of adding training in neonatal bag and mask resuscitation and oral antibiotic therapy for suspected neonatal infections to a basic preventive and promotive interventions package delivered by public sector community-based lady health workers (LHWs) in rural Pakistan...

Three series of aza-artemisinin derivatives were synthesized for studies of anticancer activity. The first series of compounds were prepared via copper(I)-catalyzed azide alkyne cycloaddition, so called "click reaction", starting from propargyl derivatives of 11-aza-artemisinin and various azides, whereas the second and third series of compounds were prepared by triazolization reaction starting from enolizable ketones and primary amines connected to artemisinin. In vitro studies of the 23 synthesized artemisinin derivatives unveiled that 9 compounds displayed antiproliferative activity in the low micromolar range, with 5d being the most promising compound showing 50% inhibition of Cem and HeLa cell growth at 0...

Arachnoid cysts are intra-arachnoid sacs filled with cerebrospinal fluid representing a rare occurence in neonates. We report the case of a suprasellar arachnoid cyst diagnosed prenatally at 21 weeks gestation on routine obstetric ultrasound. A cystic lesion was picked up incidentally at routine antenatal scan. The cyst was noted to be increasing in size over a series of radiological scans. The cyst was diagnosed as a suprasellar arachnoid cyst compressing the third ventricle and bilateral lateral ventricles...

BACKGROUND: Foreign Body Aspiration (FBA) is a serious problem in children and delays in diagnosis and management can be devastating. The history is often vague, with subtle physical and chest radiograph abnormalities. This study aims to determine the indications for bronchoscopy in children with suspected FBA and evaluate the key clinical and statistically significant predictors of FBA, based on the patients' historical, physical and radiological findings at presentation. METHODS: This is a retrospective observational study, including patients who were admitted between January 2001 to January 2011 with suspected FBA...

The binding affinity of organophosphate hydrolase enzyme (OphB) with soil particles in relation to the isoelectric point (pI) was studied. Immobilization of OphB with soil particles was observed by confocal microscopy, Fourier transform infrared spectroscopy (FT-IR), and Atomic force microscopy (AFM). The calculated pI of OphB enzyme was increased from 8.69 to 8.89, 9.04 and 9.16 by the single, double and triple mutant of OphB enzyme, respectively through the replacement of negatively charged aspartate with positively charged histidine...

Tardive dystonia (TD) is a serious side effect of antipsychotic medications, more with typical antipsychotics, that is potentially irreversible in affected patients. Studies show that newer atypical antipsychotics have a lower risk of TD. As a result, many clinicians may have developed a false sense of security when prescribing these medications. We report a case of 20-year-old male with hyperthymic temperament and borderline intellectual functioning, who developed severe TD after low dose short duration exposure to atypical antipsychotic risperidone and then olanzapine...

Artemisinin and synthetic derivatives of dihydroartemisinin are known to possess various biological activities. Post-functionalization of dihydroartemisinin with triazole heterocycles has been proven to lead to enhanced therapeutic potential. By using our newly developed triazolization strategy, a library of unexplored fused and 1,5-disubstituted 1,2,3-triazole derivatives of dihydroartemisinin were synthesized in a single step. All these newly synthesized compounds were characterized and evaluated for their anti-HIV (Human Immunodeficiency Virus) potential in MT-4 cells...

BACKGROUND: Maternal and child malnutrition is widely prevalent in low and middle income countries. In Pakistan, widespread food insecurity and malnutrition are the main contributors to poor health, low survival rates and the loss of human capital development. The nutritional status trends among children exhibit a continuous deteriorating with rates of malnutrition exceeding the WHO critical threshold. With the high prevalence of maternal and child malnutrition, it is important to identify effective preventative approaches, especially for reducing stunting in children under-five years of age...

Leishmania donovani resides within the host macrophages by dampening host defence mechanisms and thereby it modulates the host cell functions for its survival. Multiple host cell factors compete during the interplay between the host and the parasite. Roles for dual-specificity phosphatases (DUSPs) are implicated in various pathological conditions. However, the reciprocity of these DUSPs was unknown in L. donovani infection in a susceptible model. Here, we show that Mycobacterium indicus pranii (Mw), an immunomodulator, reciprocally regulates DUSP1 and DUSP6 through the TLR4 pathway...
