BACKGROUND: Burn is the most devastating condition in emergency medicine leading to chronic disabilities. This study aimed to compare the effect of Lithospermum officinale, silver sulfadiazine and alpha ointments on healing of burn wounds in rat. METHODS: Ninety-five rats were divided into 5 groups. Group 1 just underwent burn injury, and groups 2-5 received alpha ointment, silver sulfadiazine (SSD), gel base and L. officinale extract, respectively. A hot plate was used for induction of a standard 3rd degree burn wound...

Diabetic retinopathy (DR), a microvascular complication of diabetes mellitus (DM), remains as one of the major causes of vision loss worldwide. The release of pro-inflammatory cytokines and the adhesion of leukocytes to retinal capillaries are initial events in DR development. Inflammation, ER stress, oxidative stress and autophagy are major causative factors involved in the pathogenesis of DR. Diabetes associated hyperglycemia leads to mitochondrial electron transport chain dysfunction culminating in a rise in ROS generation...

Many accounts refer to insertion of finger into anus mostly for gratification from stimulation of prostate gland, but index case Mr. M. continued doing this to get rid of constipation that eventually led to feelings of guilt, stinky fingers, not able to defecate normally, and dysphoric emotions. Further research is needed to find out the phenomenology of this condition.

A swift, precise and simple HPLC bioanalytical technique with UV detection was established and validated for quantitative estimation of valsartan in human plasma. The analyte was separated from plasma by protein precipitation with acetonitrile and chromatographically separated on Zorbax SB-C18 (5μm, 4.6mm × 15cm) column. The solvent mixture system consisting of acetonitrile, water and glacial acetic acid (40:59:1 v/v), was pumped using isocratic mode at 1mL/min flow rate. Samples' detection of drug was made spectrophotometrically at a wavelength of 264nm...

Organochlorine pesticides have generated growing concern owing to their diverse toxicities. In this connection, we have evaluated toxic potential of an acaricide, dicofol (DCF) and its harmful effects on human RBCs and lymphocytes. DCF caused hemolysis and rupture of human erythrocytes as confirmed by scanning electron microscopy (SEM). Significant increase in protein oxidation, lipid peroxidation, ROS production, methemoglobin formation with enhanced activities of superoxide dismutase and catalase but decreased level of reduced glutathione were observed as a result of DCF exposure to human erythrocytes...

Genome sequence of the hyperthermophilic archaeon Pyrobaculum calidifontis contains an open reading frame, Pcal_0632, annotated as glyceraldehyde-3-phosphate dehydrogenase, which is partially overlapped with phosphoglycerate kinase. In the phylogenetic tree, Pcal_0632 clustered with phosphorylating glyceraldehyde-3-phosphate dehydrogenases characterized from hyperthermophilic archaea and exhibited highest identity of 54% with glyceraldehyde-3-phosphate dehydrogenase from Sulfolobus tokodaii. To examine biochemical function of the protein, Pcal_0632 gene was expressed in Escherichia coli and the gene product was purified...

Recent advances in Next Generation Sequencing (NGS) have provided remarkable insights into the genomic characteristics of human cancers that have spurred a revolution in the field of oncology. The mitogen-activated protein kinase pathway (MAPK) and its activating cell receptor, the receptor tyrosine kinases (RTKs), which together encompass the (RTK)-RAS-RAF-MEK-ERK axis, are central to oncogenesis. A pan-cancer genomics analysis presented in this review is made possible by large collaborative projects, including The Cancer Genome Atlas (TCGA), the International Cancer Genome Consortium (ICGC), and others...

Background: Polycystic ovary syndrome (PCOS), associated with a state of low grade chronic inflammation, depends on multiple genetic and environmental factors. Elevated levels of inflammatory markers including intercellular adhesion molecule-1 (ICAM-1) have been demonstrated in affected women. Recent evidence indicates a significant linkage between chromosome 19p13 loci and multifactorial diseases that have an inflammatory component. The aim of this study was to assess the possible association of the lys469glu (K469E) polymorphism of the ICAM-1 gene located on chromosome 19p13 with risk of PCOS in Kashmiri women...

Puberty heralds the onset of adulthood, and is fraught with complex physiological and psychological changes and emotions. In this study, we looked at the sources of information about puberty and sex education among males and females, age at which they learned about them, and the opinions on the role of schools and parents in imparting this education among medical students.A cross-sectional pilot study, using convenience sampling was conducted among 153 medical students of the Hamdard College of Medicine and Dentistry (HCM&D) in Karachi...

This study was designed to investigate selected road-dust associated heavy metals, their relations with natural and anthropogenic sources, and potential human and environmental health risks. For this purpose, 42 and 36 road-dusts samples were collected from Jalalabad and Kabul cities (Afghanistan), respectively. The following elements were found in descending concentrations: Mn, Zn, Pb, Ni, Cu, Cr, Co, and Cd in Jalalabad; and Mn, Zn, Ni, Cu, Cr, Pb, Co, and Cd in Kabul. Except for Ni, all the elemental contents were less than the Canadian permissible limits in residential/parkland soils...

A variety of factors can affect the normal development of tissues and may lead to variation in the normal compliment of teeth and development of alterations in the shape and size of teeth. These anomalies can be congenital, developmental, or acquired. Dental anomalies can present as isolated traits or be associated with systemic conditions and syndromes for which early diagnosis and genetic testing may result in better treatment outcomes and quality of life. Dentists play an essential role in the multidisciplinary management of these abnormalities...

Despite frequent scientific efforts, efficient ocular drug delivery is a major challenge for pharmaceutical scientists. Poor bioavailability of ophthalmic solutions can be overcome by using smart ophthalmic drug-delivery systems. In this research, loading and delivery of Timolol Maleate (TM) through the cornea by synthesized nanoparticles based on biopolymers (chitosan-alginate) were studied. The physico-chemical properties of these nanoparticles were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and dynamic light scattering (DLS)...

Surface acoustic waves (SAWs), are electro-mechanical waves that form on the surface of piezoelectric crystals. Because they are easy to construct and operate, SAW devices have proven to be versatile and powerful platforms for either direct chemical sensing or for upstream microfluidic processing and sample preparation. This review summarizes recent advances in the development of SAW devices for chemical sensing and analysis. The use of SAW techniques for chemical detection in both gaseous and liquid media is discussed, as well as recent fabrication advances that are pointing the way for the next generation of SAW sensors...

Masood Ahmad, Devan Makati, Sana Akbar
Obstructive sleep apnea (OSA) is a prevalent sleep disorder as is hypertension (HTN) in the 21st century with the rising incidence of obesity. Numerous studies have shown a strong association of OSA with cardiovascular morbidity and mortality. There is overwhelming evidence supporting the relationship between OSA and hypertension (HTN). The pathophysiology of HTN in OSA is complex and dependent on various factors such as sympathetic tone, renin-angiotensin-aldosterone system, endothelial dysfunction, and altered baroreceptor reflexes...
