Diabetes mellitus, a multifactorial disorder, is related to the intestinal microbiota via numerous molecular mechanisms. The vast increase in the prevalence of diabetes and its associated complications requires a natural and safe solution. There is a growing evidence of gut microbiota effi ciency in improving insulin resistance, impaired insulin secretion, and metabolic complications in diabetic patients. Probiotics are defi ned as live microorganisms that, when ingested in adequate amounts, exert health benefi ts to the host...

Type 2 diabetes mellitus is becoming increasingly prevalent worldwide and has become one of the greatest threats to global health. Bariatric surgery was initially designed to achieve weight loss and subsequently was noted to induce improvements or remission of type 2 diabetes. Currently, these bariatric operations such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most effective procedures for the treatment of obesity and type 2 diabetes mellitus worldwide. However, the specific mechanism mediating the beneficial effects of metabolic surgery has remained largely unknown...

Leptin, critical in regulation of energy metabolism, is also important for normal bone growth, maturation and turnover. Compared to wild type (WT) mice, bone mass is lower in leptin-deficient ob/ob mice; osteopenia in growing ob/ob mice is due to decreased bone accrual, and is associated with reduced longitudinal bone growth, impaired cancellous bone maturation and increased marrow adipose tissue (MAT). However, leptin deficiency also results in gonadal dysfunction, disrupting production of gonadal hormones which regulate bone growth and turnover...

The study of the concerted action of hormones and transcription factors is fundamental to understand cell differentiation and pattern formation during organ development. The root apical meristem of Arabidopsis thaliana is a useful model to address this. It has a stem cell niche near its tip conformed of a quiescent organizer and stem or initial cells around it, then a proliferation domain followed by a transition domain, where cells diminish division rate before transiting to the elongation zone; here, cells grow anisotropically prior to their final differentiation towards the plant base...

BACKGROUND: The prevalence of metabolic diseases continues to rise worldwide, with a growing recognition of metabolic dysregulation after acute inflammatory diseases such as acute pancreatitis (AP). Adipokines and cytokines play an important role in metabolism and the course of AP, but there is a paucity of research investigating their relationship with pancreatic hormones after AP. This study aimed to explore associations between pancreatic hormones with adipokines and cytokines to provide insights into the pathophysiology of altered pancreatic hormone secretion following AP...

The two main types of diabetes mellitus have distinct etiologies, yet a similar outcome: loss of islet β-cell function that is solely responsible for the secretion of the insulin hormone to reduce elevated plasma glucose toward euglycemic levels. Type 1 diabetes (T1D) has traditionally been characterized by autoimmune-mediated β-cell death leading to insulin-dependence, whereas type 2 diabetes (T2D) has hallmarks of peripheral insulin resistance, β-cell dysfunction, and cell death. However, a growing body of evidence suggests that, especially during T2D, key components of β-cell failure involves: (1) loss of cell identity, specifically proteins associated with mature cell function (e...

Context: The shoot apical meristem (SAM), origin of all aerial organs of the plant, is a restricted niche of stem cells whose growth is regulated by a complex network of genetic, hormonal and mechanical interactions. Studying the development of this area at cell level using 3D microscopy time-lapse imaging is a newly emerging key to understand the processes controlling plant morphogenesis. Computational models have been proposed to simulate those mechanisms, however their validation on real-life data is an essential step that requires an adequate representation of the growing tissue to be carried out...

Vascular complications are a leading cause of morbidity and mortality in both men and women with type 1 (T1DM) or type 2 (T2DM) diabetes mellitus, however the prevalence, progression and pathophysiology of both microvascular (nephropathy, neuropathy and retinopathy) and macrovascular [coronary heart disease (CHD), myocardial infarction, peripheral arterial disease (PAD) and stroke] disease are different in the two sexes. In general, men appear to be at a higher risk for diabetic microvascular complications, while the consequences of macrovascular complications may be greater in women...

Diabetes mellitus is widely recognised as one of the most serious metabolic diseases worldwide, and its incidence in Asian countries is growing at an alarming rate. Type 2 diabetes (T2DM) is closely associated with age, sedentary lifestyle and poor diet. In T2DM, β-cell dysfunction will occur before hyperglycaemia develops. Excessive levels of glucose, lipid and various inflammatory factors interact at the level of the pancreatic islet to promote β-cell dysfunction. Pancreatic β-cell lines have been widely utilised since the early 1980s and have contributed a large volume of important information regarding molecular, metabolic and genetic mechanisms that regulate insulin secretion...

There has been an increasing use of hormonal therapy among male-to-female (MtF) transgender individuals. This long-term hormone replacement therapy (HRT) renders MtF individuals a unique patient subgroup in terms of breast cancer risk. This case describes a MtF transgender who presented with a breast lesion concerning for malignancy following hormonal replacement therapy. The patient additionally had a strong family history of breast cancer. Final pathology revealed lobular hyperplasia in the setting of gynecomastia and pseudoangiomatous stromal hyperplasia (PASH)...

Laparoscopic ovarian drilling (LOD) has been widely utilised as an effective treatment in anovulatory women with polycystic ovarian syndrome (PCOS). However, there has been a growing concern over a possible damaging effect of this procedure on ovarian reserve. The objective of this study was to investigate the hypothesis that LOD compromises ovarian reserve as measured by post-operative changes in circulating anti-Müllerian hormone (AMH). This meta-analysis included all cohort studies as well as randomised controlled trials investigating serum AMH concentrations and other ovarian reserve markers in PCOS women undergoing LOD...

Cardiovascular disease is the leading cause of death in general population. Besides well known risk factors like hypertension, impaired glucose tolerance and dyslipidemia, growing evidence suggests that also hormonal changes in various endocrine diseases impact cardiac morphology and function. Recent studies highlight the importance of ectopic intracellular myocardial and pericardial lipid deposition, since even slight changes of these fat depots are associated with alterations in cardiac performance. In this review we overview the effects of hormones, including insulin, thyroid hormones, growth hormone and cortisol, on heart function, focusing on their impact on myocardial lipid metabolism, cardiac substrate utilization and ectopic lipid deposition, in order to highlight the important role of even subtle hormonal changes for heart function in various endocrine and metabolic diseases...

INTRODUCTION: Leydig cell tumor constitutes only about 1-3% of testicular neoplasms. There is apparently increased incidence in the last few years; one possible explanation for this phenomenon is the widespread use of ultrasound technology and the subsequent increased early detection of smaller lesions that have not been found in historical series. CASE PRESENTATION: We report a case of Leydig cell tumor of testis in a patient presenting with painless long standing slowly growing left scrotal mass who found to have intrapulmonary nodule and multiple enlarged retroperitoneal lymph nodes on staging work up...

With interest we read the recent European Journal of Clinical Investigation paper entitled "Intact FGF23 and α-Klotho during acute inflammation/sepsis in CKD patients" by E. Dounousi and coworkers (1). In their article, the authors analyse the association between acute infection and plasma levels of the phosphaturic hormone fibroblast growth factor 23 (FGF-23). The physiological regulation of FGF-23 is not fully understood so far, and hence novel pathophysiological data are of importance. Particularly the link between FGF23 and inflammation is a growing field...

A new purple quail-like (q-lp) mutant found from the plain silkworm strain 932VR has pigment dots on the epidermis similar to the pigment mutant quail (q). In addition, q-lp mutant larvae are inactive, consume little and grow slowly, with a high death rate and other developmental abnormalities. Pigmentation of the silkworm epidermis consists of melanin, ommochrome and pteridine. Silkworm development is regulated by ecdysone and juvenile hormone. In this study, we performed RNA-Seq on the epidermis of the q-lp mutant in the 4th instar during molting, with 932VR serving as the control...

BACKGROUND: The movement of plant roots within the soil is key to their ability to interact with the environment and maximize anchorage and nutrient acquisition. Directional growth of roots occurs by a combination of sensing external cues, hormonal signaling and cytoskeletal changes in the root cells. Roots growing on slanted, impenetrable growth medium display a characteristic waving and skewing, and mutants with deviations in these phenotypes assist in identifying genes required for root movement...

OBJECTIVE Pituitary adenomas are benign, slow-growing tumors that cause symptoms either through mass effect or hormone overproduction. The decision to operate on a healthy young person is relatively straightforward. In the elderly population, however, the risks of complications may increase, rendering the decision more complex. Few studies have documented the risks of surgery using the endonasal endoscopic approach in a large number of elderly patients. The purpose of this study was to audit a single center's data regarding outcomes of purely endoscopic endonasal transsphenoidal resection of pituitary adenomas in elderly patients and to compare them to the current literature...

INTRODUCTION: The growing belief that endocrine abnormalities may underlie many mental conditions has led to increased use of imaging and hormonal assays in patients attending to psychiatric OPDs. People who are in an acute phase of a psychiatric disorder show Hypothalamic Pituitary Adrenal (HPA) axis hyperactivity, but the precise underlying central mechanisms are unclear. AIM: To assess the pituitary gland volume variations in patients presenting with new onset acute psychiatric illness in comparison with age and gender matched controls by using MRI...
