We describe a case of an Asian-Indian female patient who presented to us with abnormal fat accumulations in the torso and upper arms following indiscriminate use of corticosteroid and anabolic steroids for about 7 years. Despite prolonged steroid use, the patient did not display cushingoid phenotype or metabolic decompensation. Bone density, echocardiography, and ultrasonogram of the liver were also normal with no evidence of excess pericardial fat, hepatic steatosis, or peliosis hepatis.

Objectives: The place of a child's death is an indicator of the quality of paediatric palliative and end-of-life care. This study aimed to identify the choices of parents about the place of death of their children with cancer and to evaluate whether they had any regrets about their choices retrospectively.

Material And Methods: All children who were treated in our centre for the past 9 years with palliative intent treatment to improve their quality of life were included in this study.

Aim: The present study aimed at evaluating the increase in the rate of tooth movement by increasing the number and frequency of micro-osteoperforations (MOPs).

Materials And Methods: The study was a single-center, split-mouth, randomized controlled trial. A total of 20 patients were included in the study who had fully erupted maxillary canines with class I molar canine relationship and a bimaxillary protrusion that required the removal of both maxillary and mandibular first premolars.

Aim: The aim of the study is to compare the efficiency of Michigan (MI) varnish containing casein phosphopeptide (CPP) and amorphous calcium phosphate (ACP) and Fluoritop containing sodium fluoride (5% NaF) in the prevention and remineralization of white spot lesions (WSLs) around orthodontic brackets at days 28 and 56 after bonding.

Materials And Methods: A total of 30 patients were selected and divided into two groups I (MI varnish) II (Fluoritop varnish) of 15 patients in each group. All the patients were bonded and then varnish was applied around the brackets.

Non-Hispanic Black (NHB) and Hispanic patients with acute myeloid leukemia (AML) have higher mortality rates than non-Hispanic White (NHW) patients despite more favorable genetics and younger age. A discrete survival analysis was performed on 822 adult patients with AML from 6 urban cancer centers and revealed inferior survival among NHB (hazard ratio [HR] = 1.59; 95% confidence interval [CI]: 1.

A series of isoxazoline derivatives (4a-i) was synthesized from the reaction of 3-(4-fluorophenyl)-1-phenylprop-2-en-1-one derivatives (4a-i) and hydroxylamine hydrochloride in ethanol at reflux conditions. The compounds were confirmed by spectral (IR, 1H & 13C NMR) and elemental analysis. The compounds were screened for their in vitro antioxidant activity against DPPH.

Non-secretory multiple myeloma (NSMM) constitutes a distinct entity of multiple myeloma characterized by the absence of detectable monoclonal protein and rarely an absence of free light chains in the serum and urine. Given its rarity, the genomic landscape, clinical course, and prognosis of NSSM are not well characterized. Here, we report a case of a patient with relapsed and refractory NSMM with brain metastasis harboring a TFG-ALK fusion showing a dramatic and durable (over two years) response to commercially available anaplastic lymphoma kinase (ALK) inhibitors.

Many genetic diseases are caused by single-nucleotide polymorphisms. Base editors can correct these mutations at single-nucleotide resolution, but until recently, only allowed for transition edits, addressing four out of twelve possible DNA base substitutions. Here, we develop a class of C:G to G:C Base Editors to create single-base genomic transversions in human cells.

Conjugated dendrimers decorated with 5,5-difluoro-10-(4-(prop-2-ynyloxy)phenyl)-5-dipyrrolo[1,2-:1',2'-][1,3,2]diazaborinin-4-ium-5-uide, usually known as boron dipyrromethene (BODIPY), have been synthesized and their application as photosensitizer in dye sensitized solar cells (DSSCs) has been evaluated. Third generation triazole bridged BODIPY dendrimers show higher light energy harvesting efficiency of 2.5% better than the first and second generation dendrimers, when used as a dye material in solar cells.

The stable, water-soluble, and fluorescent sub 1 nm sized poly(acrylic acid)-capped copper nanoparticles (PAACC NPs) were synthesized using a high-intensity ultrasound sonication (30 KHz) method. The reduction of copper NPs from copper(II) salt by mild reducing agent l-ascorbic acid in an aqueous medium was achieved in the presence of poly(acrylic acid). The PAACC NPs were characterized by DRS UV-visible, XPS, PL, FESEM, and HRTEM techniques.

Aim To compare the periodontal status in relation to the lower anteriors of patients between labial and lingual orthodontic therapy. Materials and methods The study includes a total of 20 patients in the age group of 20-30 years. All the included patients were selected with limited lower anterior crowding within 0-8 mm.

A convenient and efficient method for the regioselective macrocyclization of triazole bridged spiropyrrolidine-oxindole, and bis-spiropyrrolizidine-oxindole derivatives was accomplished through intra and self-intermolecular [3 + 2] cycloaddition of azomethine ylides. The chalcone isatin precursors 9a-i required for the click reaction were obtained from the reaction of -alkylazidoisatin 4 and propargyloxy chalcone 8a-i which in turn were obtained by the aldol condensation of propargyloxy salicylaldehyde 6 and substituted methyl ketones 7a-i. The regio- and stereochemical outcome of the cycloadducts were assigned based on 2D NMR and confirmed by single crystal XRD analysis.

Edible microalgae have potential as low-cost cell factories for the production and oral delivery of recombinant proteins such as vaccines, anti-bacterials and gut-active enzymes that are beneficial to farmed animals including livestock, poultry and fish. However, a major economic and technical problem associated with large-scale cultivation of microalgae, even in closed photobioreactors, is invasion by contaminating microorganisms. Avoiding this requires costly media sterilisation, aseptic techniques during set-up and implementation of 'crop-protection' strategies during cultivation.

(S)-BINOL cored dendrimers 1-3 with a rhodamine B surface group and triazole bridging unit were synthesized up to second generation in good yield by convergent synthesis through click chemistry. The chiro-optical property of the synthesized dendrimers reveals that the specific rotation increases as the order of dendrimer increases from the zeroth generation to the second generation dendrimer. The electrochemical properties of the dendrimers 1, 2 and 3 showed quasi-reversible behavior in cyclic voltammetry.

Dysfunction of virus-specific CD4 T cells in chronic human infections is poorly understood. We performed genome-wide transcriptional analyses and functional assays of CD4 T cells specific for human immunodeficiency virus (HIV) from HIV-infected people before and after initiation of antiretroviral therapy (ART). A follicular helper T cell (T cell)-like profile characterized HIV-specific CD4 T cells in viremic infection.

The most common brain disorder of late life is Alzheimer's disease (AD), which is highly complicating dementia. There are several drug targets which are reported to control the severe level of AD; notably, acetylcholinesterase, β-Secretase and glycogen synthase kinase enzymes are approached as a good drug targets for AD. Hence, the present study mainly focused to discover newly synthesized molecule (7-propyl-6H-pyrano[3,2-c:5,6-c']dichromene-6,8(7H)-dione) as a potential triplet acting drug for above said enzymes through the analysis of X-ray crystallography, molecular docking, molecular dynamics and quantum chemical calculation.

Objective: To implement a daily rounding tool in a pediatric intensive care unit (PICU) to improve the discussion performance of identified clinical elements. We hypothesized that a semi-structured rounding tool created by a multidisciplinary team would be successfully implemented and sustained in the PICU.

Patients And Methods: A pre-post interventional study was conducted in a multidisciplinary medical-surgical PICU.

Biofoundries have enabled the ability to automate the construction of genetic constructs using computer-aided design. In this study, we have developed the methodology required to abstract and automate the construction of yeast-compatible designs. We demonstrate the use of our in-house software tool, AMOS, to coordinate with design software, JMP, and robotic liquid handling platforms to successfully manage the construction of a library of 88 yeast expression plasmids.
