Diabetes Mellitus is characterized by numerous metabolic disorders, which have in common the serum elevation of glucose, caused for a pancreatic malfunction in insulin secretion and / or its action. It is a non-communicable disease, considered major public health problems and generalized growth worldwide, being a chronic disease, which can generate a high treatment cost. Metabolic surgery is a safe treatment, regulated by the Federal Council of Medicine and useful in treating people with BMI over 30 years of age, who are unable to control pathologies associated with obesity, especially type 2 diabetes. The general objective of this study is to understand through a literature review the main impacts of metabolic surgery about the remission of DM 2. This present study it is an exploratory and descriptive study carried out through a literature review. Data were collected through research in virtual health databases, at the Virtual Health Library - VHL, Latin American and Caribbean Health Sciences Information System, LILACS, National Library of Medicine - MEDLINE, Scielo, USP database, PUBMED theses and books. Metabolic surgery proof be a good and effective treatment for having and maintaining good weight loss, as well as a significant clinical and metabolic improvement that extends beyond weight loss. Metabolic surgery is a satisfactory way of achieving long-term weight reduction in obese individuals, increasing survival for these patients. Obese patients with DM2 have a long-term remission of DM2 after bariatric / metabolic surgery. Therefore, it concludes that such procedure is effective in the treatment of the disease and other diseases associated with obesity. 1.
The scarcity of human cadaver islets for transplantation in patients with Diabetes Mellitus (DM) has necessitated the search for alternative islet sources. With advancing islet biology research, islet-like clusters (ILCs) derived from stem cells have demonstrated potential for treating DM and in novel drug discovery programs for drug and cytotoxicity testing. In vitro differentiation of ILCs from stem cells also provides an opportunity to mimic the in vivo islet developmental pathways. In vitro derived ILCs are often considered immature,as they do not respond to glucose challenge efficiently. However, the in vitro and in vivo performance of ILCs can be imroved by pharmacological preconditioning.
In this review, we discuss how ILCs generated from human postnatal tissues can be utilized as an in-vitro model to study cytotoxicity, drug screening and enhancement of transplantation efficacy. Use of human cadevar islets is not permitted for research purposes in India. Under these restrictions, the application of ILCs in drug screening and their role in complementing, reducing, and replacing animal testing will evolve a reliable platform in vitro screening as well as for stem cell-based treatment in DM.

Inflammation is a multifactorial process reflecting the response of the organism to various stimuli and is associated with a number of disorders such as arthritis, asthma and psoriasis, which require long-lasting or repeated treatment.
The aim of this paper is to evaluate the anti-inflammatory activity of previous synthesized thiazole-based chalcone derivatives.
Chalcones were synthesized via Cliazen-Schmidt condensation1-(4-methyl-2- alkylamino)thiazol-5-yl) ethanone with a corresponding aromatic aldehyde. For the evaluation of possible anti-inflammatory activity, carrageenan mouse paw edema was used.
Eight out of thirteen tested chalcones showed anti-inflammatory activity in a range of 51- 55%. Prediction of toxicity revealed that these compounds are not toxic.
In general, it can be concluded that these compounds can be used for further modifications in order to develop more active and safe agents.

Mainly, in the past years, diverse conjugates carrying this biologically valuable core have been reported due to their attractive fungicidal potential and potent effects on various infective targets. SR-717 order Hence, hybridization of 1,2,3-triazole with other antimicrobial pharmacophores appears to be a judicious strategy to develop new effective anti-fungal candidates to combat the emergence of drug-sensitive and drug-resistant infectious diseases. Thus, the current review highlights the recent advances of this promising category of 1,2,3-triazole-containing hybrids incorporating diverse varieties of bioactive heterocycles such as conozole, coumarin, imidazole, benzimidazole, pyrazole, indole, oxindole, chromene, pyrane, quinazoline, chalcone, isoflavone, carbohydrates, and amides. It underlies their inhibition behavior against a wide array of infectious fungal species during 2015-2020.
Due to the scarcity of longitudinal data, the morphologic development of intracranial aneurysms (IAs) during their natural history remains poorly understood. However, longitudinal information can often be inferred from cross-sectional datasets as demonstrated by anatomists' use of geometric morphometrics to build evolutionary trees, reconstructing species inter-relationships based on morphologic landmarks.
We adopted these tools to analyze cross-sectional image data and infer relationships between IA morphologies.
On 3D reconstructions of 52 middle cerebral arteries (MCA) IAs (9 ruptured) and 10 IAfree MCAs (baseline geometries), 7 semi-automated landmarks were placed at the proximal parent artery and maximum height. From these, 64 additional landmarks were computationally generated to create a 71-landmark point cloud of 213 xyz coordinates. link2 This data was normalized by Procrustes transformation and used in the principal component analysis, hierarchical clustering, and phylogenetic analyses.
Principal component analysis showed separation of IA-free MCA geometries and grouping of ruptured IAs from unruptured IAs. Hierarchical clustering delineated a cluster of only unruptured IAs that were significantly smaller and more spherical than clusters that had ruptured IAs. Phylogenetic classification placed ruptured IAs more distally in the tree than unruptured IAs, indicating greater shape derivation. Groups of unruptured IAs were observed, but ruptured IAs were invariably found in mixed lineages with unruptured IAs, suggesting that some pathways of shape change may be benign while others are more associated with rupture.
Geometric morphometric analyses of larger datasets may indicate particular pathways of shape change leading toward aneurysm rupture versus stabilization.

The aim of this study was to evaluate whether the VNTR intron 4b/4a variant in the eNOS gene is associated with type 2 diabetes mellitus (T2DM) and DPN.
A total of 598 subjects were enrolled in the study. eNOS VNTR 4b/4a variant was genotyped by polymerase chain reaction (PCR) method.
eNOS VNTR intron 4b/4b genotype and b allele increased in patients with both DPN and T2DM compared healthy controls (p=0.0005, OR1.94, p= 0.000002, OR4.10, respectively). 4a/4b genotype was more prevalent in controls than in DPN and T2DM patients (p=0.00008, OR0.46; p=0.000004, OR0.24, respectively). eNOS VNTR b allele was more common in DPN patients and T2DM patients compared with controls (p=0.007, p=0.00002, respectively).
The eNOS VNTR "4b/4b" homozygous genotype and hence "4b"allele as a genetic risk factor for T2DM and DPN, which may serve as a useful marker of increased susceptibility to the risk of these disorders.

Paclitaxel (PTX) is heavily relied on as a frontline chemotherapy in breast cancer treatment, especially in advanced metastatic cancer. Generation of resistance to PTX often derails clinical management and adversely affects patient outcomes. Defining the molecular mechanism underlying PTX resistance is mostly sought for to aid in overcoming resistance, and this oriented research has led to the understanding of a range of PTX resistance related therapeutic targets. PTX resistance pathways that involve major regulatory proteins/RNAs like RNF8/Twist/ROR1, TLR, ErbB3/ErbB2, BRCA1-IRIS, MENA, LIN9, MiRNA, FoxM1 and IRAK1 have expanded the complexity of resistance mechanisms, and brought newer insights for development of drug targets. This resistance related targets can be dealt with synthetic/natural therapeutics in combination with PTX. The present review encompasses recent understanding of PTX resistance mechanisms in breast cancer and possible therapeutic combinations to overcome resistance.The field of nuclear medicine is rapidly evolving due to the high demand of radiopharmaceuticals for diagnostic and therapeutic applications. The availability of a vast array of radioisotopes, improvement in radiolabeling strategies, and advancements in detection systems have also contributed to the progress in this field. link3 Radiopharmaceuticals are mainly classified based on their application as diagnostic or therapeutic radiopharmaceuticals. These are available either as ready to use preparations or prepared at hospital radiopharmacy either using automated synthesis modules or by using freeze-dried cold kit formulations. Availability of freeze-dried cold kits for preparation of varied radiopharmaceuticals for targeting various organs and tissues played an essential role in the extensive use of 99mTc radiopharmaceuticals for diagnostic imaging by single-photon emission computed tomography (SPECT) imaging. Cold kits are especially suitable for the preparation of radiopharmaceuticals labeled with isotopes like 177Lu with relatively long half-life or radionuclides produced by radioisotope generators.
