Toxicology deals with the measurement and analysis of toxins. It is itself a vast branch of science, though it has several branches and one of these is forensic toxicology. Forensic toxicology is a branch of toxicology that lines up with other disciplines, namely clinical chemistry, postmortem forensic toxicology, human performance toxicology and forensic drug testing, providing medical jurisprudence of adverse effects such as drug abuse, poisoning and death. The key role of forensic toxicology is to identify and analyse the toxin compounds found during adverse events. This review paper aims to draw an idea about the toxin, in the collected biological chemical samples such as urine samples and their effects on their day-to-day life

Intravascular large B-cell lymphoma (IVBCL) is a rare but aggressive form of non-Hodgkin lymphoma. It is characterized by the malignant proliferation of lymphocytic tumor cells in the lumens of capillaries, small arterioles, and post-capillary venules. There exists two clinical variants: the Asian variant and the Western variant. The former is associated with neurologic and dermatologic signs and symptoms, whereas the latter often presents with splenomegaly, jaundice, and hemophagocytes. Lymphadenopathy is uncommon, and patients typically have nonspecific symptom

Grapes (Vitis vinifera L.) are among the most commonly cultivated horticultural crops on the earth covering an area of 7.5 million hectares with around 70 million tons production. Grapes being highly nutritious are majorly utilized in making beverages or used as fresh and raisin. In today’s world, the most concerned topic in agriculture is continuous change in climatic conditions leading to several negative social, ecological, economical and biological problems. Grapes are delicate fruits, their vines are sensitive towards extremes in temperature, water, heat, duration and intensity of light exposure as well as carbon dioxide and humidity alterations. Hence, one can shift to drought and heat tolerant varieties and certain training and pruning methods suitable to the prevailing environmental conditions. Vineyard management practices, including farm mechanization can be amended for improving the gains, while reducing the input

Sugarcane is a vital cash crop grown in about 200 tropical and sub-tropical countries around the world. Due to its high rates of occupational diseases, accidents, and fatalities the agro industry is regarded as one of the most hazardous industries despite being one of the essential sectors globally regarding food supply and workforce. Most of the world's cane sugar crop is produced In Low- and Middle-Income Countries (LMIC), such as Sudan, where agriculture and farming are still the main sources of income and managing occupational health and safety is challenging

The problem of excess body weight is becoming an epidemic in the general population, especially among children aged to 12 years old. Efforts are being made to find a way to retreat the unfavorable changes related with obesity. This problem is escalating, and the direction of effective protective actions is not sufficiently recognized. The research presented in this study demonstrate the range of changes in overweight and obese children after an 8 weeks of circuit training program, with simultaneous parental education on modifying their children dietary habits

spinal muscular atrophy is an autosomal recessive disorder characterized by degeneration of alpha motor in anterior horn cells of brain and spinal cord, which results in muscular atrophy, hypotonia, fasciculations, areflexia, paralysis and even death in most severe cases. The underlying cause of this disease is biallelic loss of survival motor neuron 1 (SMN1) gene. Depending upon the clinical features & patient's age, SMA is classified into different distinctive sub types

Eczema herpeticum (EH) is a skin infection caused by the herpes simplex virus (HSV) that occurs in individuals with atopic dermatitis. It is characterized by the sudden appearance of vesicles and erosions with crusts over areas affected by eczema. EH can range from mild and self-limiting in healthy adults to life-threatening in children, infants, and immunocompromised patients. Early treatment with antiviral therapy is crucial in preventing complications and mortality. EH is primarily caused by a superinfection of HSV, usually HSV-1, in individuals with atopic dermatitis. Reactivation of HSV is more common than primary infection. Patients with atopic dermatitis are more susceptible to skin infections due to impaired skin barrier function and immune dysregulation. Disseminated cutaneous HSV infection can also occur in individuals with other forms of dermatitis, known as Kaposi varicelliform eruption (KVE)

Leukocytoclastic Vasculitis (LCV) characterizes various small vessel vasculitis types primarily affecting the skin, with occasional internal organ involvement. This inflammation involves immune-complex deposition within dermal capillaries and venues. Although idiopathic in origin, potential triggers, including antibiotic-related factors, must be considered. LCV presents across a spectrum of severity, sometimes extending to ulcers. Diagnosis involves clinical assessment, history, lab tests, and crucially, skin biopsy.

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
