The nature of gene mutations induced by ionizing radiation in germ cells and transmitted to offspring remains one of the most important problems in radiation genetics of higher eukaryotes. The data accumulated in this field were obtained by different authors under different experimental conditions which does not give a complete insight about the nature of radiation-induced inherited mutations at different genome levels (chromosome, gene, DNA). 

Pulmonary embolism (PE) is a blockage of blood flow in the pulmonary artery bed that can result in a life-threatening and potentially reversible right ventricular failure [1]. PE remains one of the leading causes of poor prognosis and death, particularly when a shock or right ventricular failure occurs [2]. According to studies, PE is generally manifested in a nonspecific manner

Observational studies have demonstrated association of metformin with reduced cancer incidence and mortality in multiple cancer types, including gastrointestinal (GI) malignancies. Anti-neoplastic effects of metformin are believed through many mechanisms including activation of AMP-activated protein kinase, which controls mammalian target of rapamycin (mTOR) growth regulatory pathway.

We have recently published a case of spontaneous gastric decompression and resolution of an infected walled-off pancreatic necrosis (WOPN). According to the so-called “step-up approach”, which is a staged and multidisciplinary approach for the treatment of necrotizing pancreatitis, we have outlined the need of treating WOPN and their complications according to the clinical course of the patients and not only to radiological and laboratory findings.

Liver fibrosis is a reversible wound-healing response in which a variety of cells and factors are involved in and results in excessive deposition of extracellular matrix (ECM). Cirrhosis is one of the significant causes of portal hypertension and end-stage liver disease, and it is the 14th most common cause of death around the world. Approximately 1.03 million people worldwide die from liver cirrhosis every year.

Patients of all ages with motor disorders expect highquality assessments and evidence- based treatment [1]. In university hospitals, alongside medical training and treatment of patients, research [2] is an integral part of the skills for medical professionals e.g. doctors, nurses, occupational therapists and physiotherapists.

The gut microbiome or gut flora is a vast community of microorganisms such as bacteria, viruses, protozoa, and fungi that inhabit the digestive tract of the human and other animals. In the human body, bacterial species colonize into the oral cavity, skin, vagina, and placenta, however, the largest population of microorganisms resides in the intestine. The majority of gut microbiota belong to the phyla Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria.

Objective: To investigate the effect of low progesterone (P) level on the day of human chorionic gonadotropin (hCG) injection on the outcome of in vitro fertilization (IVF) with GnRH- agonist (GnRH-a) long protocol. Methods: A retrospective study was conducted in a reproductive medicine center of University-affiliated teaching hospital. 1115 women included were divided into two groups according to the P level: Group 1 (233 women with P level ≤ 0.5 ng/ml, and Group 2 (882 women with P level >0.5, ≤ 1.5 ng/ml). 

However, the entire coagulation cascade is dysfunctional, in progressed chronic diabetes and cancer patients. Platelets (PLTs) in type 2 diabetic (DT2) involved in Thrombosis and Haemostasis (T&H) of individuals adhere to vascular endothelium and aggregate more voluntarily than those in healthy individuals, as are abnormalities in the microvascular and macrovascular circulations. However it is already known that the circulating PLTs are essential for T&H, inflammation growth factors delivery, regeneration; and knowledge of their function is fundamental to understanding the pathophysiology of vascular disease in diabetes and cancer-related diseases.

Peripheral nerves have been shown to modulate the growth and spread of tumours in the prostate, feeding both cancer cells and the stroma in the tumour environment. Several in vitro and in vivo studies have reported the effect of botulinum toxin (BT) on tumour tissue in the prostate. BT in humans has been observed to cause increased apoptosis of cancer cells, with morphological changes characterized by extensive degenerative and atrophic areas of cancer, reduced cytoplasm, and pyknotic nuclei, compared to the characteristics of cancer tissues injected with saline solution.

Being a sophisticated and highly organized living system, mammals harbor a large number of biomolecular machineries which represent a dynamic and complex network of interconnections responsible for the effective operation, development and survivability of their body cells. Sphingolipids are a special class of lipids in eukaryotic cells, which have recently gained the attention of researchers because of their involvement in several fundamental processes of living cells, including proliferation

In South Africa, new amended regulations required a review of complementary and alternative medicine (CAMs) call-up for registration from November 2013. This impacted traditional healers (THs)’ compliance with the regulatory authorities’ on the good manufacturing practice which in return affected the public’s access to CAMs. This investigation embraces methods, THs use to diagnose and treat diabetes (DM) in Mamelodi. Furthermore, it assesses what their purported medications comprise of.

Despite the curious advancement in medical science and therapeutics, tuberculosis (TB) persist the primary factor of mortality than any other infectious disease and socioeconomic disaster for millions of people around the world. According to the World Health Organization (WHO), World’s One-third of the population is infected with this disease and of these, 8 to 10 million people develop active disease and 2 million people die each year and the rest of the infected people remain asymptomatic.

Galectin-3 (Gal-3), the only chimera-like galectin, has three structural domains: (a) the NH2 terminal domain containing serine phosphorylation, important for nuclear localization, secretion and oligomerization; (b) a sequence susceptible to metalloprotease (MMP) cleavage; and (c) a C-terminal domain containing the carbohydrate recognition domain (CRD) and an anti-death motif.

Prevalence of diabetes is increasing. Diabetes is more prevalent in the socially deprived, ethnic minority population (based on continuing rise in elderly population, growing obesity and BME groups). Compliance is a major stumbling block in the management of most long-term conditions including diabetes.

The local and peritoneal recurrence play a vital role in the natural history of the evolution of gastrointestinal and ovarian neoplasms. Different methods of applying intraperitoneal chemotherapy were used perioperatively to consolidate or control peritoneal carcinomatosis [1]. The use of chemotherapy directly in the peritoneal cavity allows the direct action of the therapeutic agent in the metastatic nodules, increasing the local concentration with a limited increase in the systemic concentration. 

Diabetes mellitus (DM) is an age-related metabolic disorder affecting 347 million people in modern society. Expanding its prevalence beyond developed countries, DM has emerged as a global public health issue associated with a high morbidity and mortality.

Aging is a complicated process not yet fully understood. Driven by a variety of stressors such as infectious agents, radiation, intracellular stress, and stressing metabolic conditions, molecular damage occurs over time [1]. Among many consequences, age-related unchecked molecular damage leads to immunosenescence, a hallmark of aging. Traditionally defined as a declining function of the immune system, immunosenescence is a term that includes the effect of aging on adaptive and innate immunity [2].

Postmenopausal hyperhidrosis (PMH) is an important differential diagnosis to vasomotor symptoms (VMS) in menopause. The objective is to describe the differences in clinical presentation and treatment of the two conditions. Patients suffering from PMH represent a unique cohort of patients with primary hyperhidrosis and should therefore not be treated in the same way as those displaying VMS during menopause.

Diabetes mellitus is a common metabolic disorder that present with abnormal glucose metabolism. This metabolic disease is prevalent in many countries, worldwide. It is no doubt there might be a chance that diabetes mellitus might co-occur with other medical problems.
