Familial Hypokalemic Periodic Paralysis with Myotonic Phenomenon : Case Report

Hypokalemic Periodic Paralysis (HypoPP) is a rare disease whereby voltage-gated ion channels are mutated and it is characterized by episodic flaccid paralysis concomitant to variations in blood potassium levels. Attacks usually happen after exercise or high carbohydrate meals. The diagnosis is made with laboratory data which helps to exclude other causes and confirm low serum potassium or myotonia on eletromyography (EMG).

The Role of Nanotechnology in Semiconductor Industry: Review Article

Nanotechnology is now the key area of technology to create and manipulate materials at the nanometre (nm or 10-9 m) scale either by bottom up from single groups of atoms to bulk matter or by top down which is reducing bulk materials to a group of atom. Now a days it is being used or considered for use for fabricating and constructing many efficient electronic devices which have extremely large surface area to volume ratio, this makes a large number of surface or interfacial atoms, resulting in more surface dependent material properties specially this technology is used in semiconductor industry or solar cell industry.

Wildlife Forensic: Current Techniques and their limitations

The wildlife includes undomesticated and diverse forms of floral and faunal species, which is essential for ecological balance and human survival. The poaching and illegal trade has resulted in sharp decline of many wild species of flora and fauna around the world. The need of the time therefore is to utterly focus on wildlife protection for the sustainable development of biosphere and future viability of human beings. In this review we have focused on different techniques being utilized in wildlife forensic science for identification of wildlife species as well as their geographical origin. These techniques can be employed to control the wildlife crimes and convict the criminals involved in illegal trade of wildlife flora, fauna and their products. These techniques include footprints analyses, morphological and anatomical studies,

Obesity and its Correlates among Junior High School Children in the Accra Metropolis

The prevalence of obesity is on the increase worldwide due to changes in diet and physical activity patterns. Childhood obesity is now a major public health challenge in advanced economies. Obesity in childhood tends to persist into adulthood and to predispose to non-communicable diseases. There is little data on childhood obesity and its correlates and determinants in sub-Saharan Africa. A cross-sectional study was carried out using simple random sampling technique to select 260 junior high school children aged 11-15 years from six basic schools (n=768) from three different socioeconomic (low, middle, high) areas of Accra, the capital city of Ghana.

Effects of Mutual Interaction between Constituent Elements on Phase Formation of High Entropy Alloys

High entropy alloys (HEAs) are alloys that contains multiple elements, often five or more principal elements in equiatomic or near equiatomic ratio with or without minor elements. As felt from the name, high mixing entropy is the sole parameter to decide the solid solution alloy formation in HEAs but, the mutual interaction between elements are key parameters to predict the phase formation in HEAs as proposed by some researchers. In this review the guideline for alloy design in HEAs for the formation of solid solution phases are proposed on basis of atomic size difference (δ), mixing entropy (ΔSmix), mixing enthalpy (ΔHmix), valence electron concentration (VEC) and electronegativity difference (Δχ).

Long Exposure to CdS-Dextrin Nanoparticles Induces an Immunomodulatory and Anti-Inflammatory Effect in Rats

Male Wistar rats were treated daily and intraperitoneally with CdS-Dextrin nanoparticles (100 μg/kg) during 30, 60, and 90 days. The effect of subacute and chronic administration of CdS-Dextrin nanoparticles on CD4/CD8 subpopulations of thymocytes, spleen-derived T cells, and peripheral blood CD4/CD8/CD3 T cells were analyzed by flow cytometer using a Rat T Lymphocyte Cocktail. An indirect ELISA kit analyzed cytokine Th1/Th2 levels. A DNA content and cell cycle analysis was carried out in bone marrow cells by flow cytometry. We also analyzed the presence of CdS-Dextrin nanoparticles in the thymus and spleen.

The Evaluation of Functional Mobility Chronic Hemiparetics Submitted to Group Physiotherapy in the Training Circuit Format

Objective: To evaluate the functional mobility of chronic hemiparesis sufferers who undergo 12 weeks of GPCT. IntroductionMethod: We selected 10 chronic hemiparetic patients, aged 21 or over with a medical referral and one-sided hemiparesis with an injury time of ≥12months, capable of walking with or without help and having the ability to perform walking tests. Interviews to collect personal data were conducted, which were then evaluated by Time up & go (TUG) which recorded the time taken for the patient to stand up from a chair, walk 3 meters, return and sit constituting the initial assessment (AV1) and after 12 weeks of intervention with GPCT the final evaluations were taken (AV2).

Infective Endocarditis at Tricuspid Valve in CHD: What are its Characteristics? What is the Pathophysiology?

Infective endocarditis (IE) is a serious infectious disease that carries a high mortality rate. We report the case of 74-year-old female who is a chronic hemodialysis patient, and was presented with tricuspid valve endocarditis (TVIE) with central venous catheter, due to an Enterobacter Cloacae, which is a non-HACEK Gram-negative bacilli (GNB) and has been reported to be an extremely rare pathogen of IE. The patient was treated with imipenem and teicoplanin for a four-week period, with negative Blood culture and normal C reactive protein (CRP) levels at the end. The aim of our study is to understand the pathophysiology of the IE in chronic renal failure (CRF) especially at the tricuspid valve (TV), and to determine the clinical, biological characteristics and therapeutic modalities.

Gut Microbiomes of Pigs Grown in Organic and Conventional Dietary Regimens

In animal production, antibiotics are used at sub-therapeutic and therapeutic levels for growth promotion and disease prevention. Using antibiotics can result in selecting for drug resistant microorganisms that may spread to humans through consumption of contaminated food. Lately, an increased interest in organic farming, where animals are grown without antibiotics, has been popular amongst the consumers. It is believed that organic farming will reduce antimicrobial resistance in microorganisms. However, the animals grown organically may be prone to diseases, and other microorganisms may thrive in the gut, that may be potentially harmful to humans. We analyzed the DNA of fecal samples of pigs grown under conventional and organic dietary regimens and detected the presence of genes that causes antibiotic resistance.

Targeted Killing of Streptococcus mutans in Biofilms by a Pheromone Guided Antimicrobial Peptide HP30

Streptococcus mutans is a leading cariogenic pathogen of dental caries worldwide. Clinically, eliminating S. mutans from dental biofilms using antibiotics is not practical, because these agents indiscriminately kill other members of the resident flora, leading to ecological disruption and other negative clinical consequences. To develop target-specific antimicrobials, we evaluated several fusion peptides and identified a new peptide HP30 that showed a high selectivity for targeted killing of S. mutans.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
