Exercise interventions in patients with multiple myeloma: a scoping review.

Background: Patients with multiple myeloma (MM) frequently experience impaired motor function and reduced quality of life. While exercise interventions play a vital role, no standardized guidelines tailored specifically to MM patients currently exist. This article reviews the scope of exercise interventions for patients with MM and further analyzes the current situation, providing references for early rehabilitation.

Adsorption characteristics of sulfate reducing bacteria Clostridium sp. on lignite surface.

Biogenic coal bed methane has attracted great attention in recent years. During the process of biogas production, the interaction between microorganisms and coal is a crucial step. Sulfate-reducing bacteria (SRB) play an important role in biogas production.

A novel homozygous intronic variant in CDT1 that alters splicing causes Meier-Gorlin syndrome, and a review of published mutations and growth hormone treatments.

Background: Meier-Gorlin syndrome (MGORS) is a rare autosomal inherited form of primordial dwarfism. Pathogenic variants in 13 genes involved in DNA replication initiation have been identified in this disease, but homozygous intronic variants have never been reported. Additionally, whether growth hormone (GH) treatment can increase the height of children with MGORS is unclear.

C5aR1-positive adipocytes mediate non-shivering thermogenesis in neonatal mice.

Brown adipose tissue (BAT) plays an important role in maintaining body temperature in newborn mammals; however, its mechanisms remain poorly understood. Here, we report the identification of a special population of brown adipose tissue-derived stromal cells (ASCs) in neonatal mice that highly express CD45 and can be differentiated into adipocytes with lower thermogenic ability. These CD45 adipocytes also characteristically contained complement C5a receptor 1(C5aR1) on the cell membrane.

Acute inhibition of iron-sulfur cluster biosynthesis disrupts metabolic flexibility in mice.

Unlabelled: Iron-sulfur clusters (ISCs) are cell-essential cofactors present in ∼60 proteins including subunits of OXPHOS complexes I-III, DNA polymerases, and iron-sensing proteins. Dysfunctions in ISC biosynthesis are associated with anemias, neurodegenerative disorders, and metabolic diseases. To assess consequences of acute ISC inhibition in a whole body setting, we developed a mouse model in which key ISC biosynthetic enzyme NFS1 can be acutely and reversibly suppressed.

Photosynthetic response of and sp. 1710 to zinc toxicity.

Zinc (Zn) is an essential trace element but can lead to water contamination and ecological deterioration when present in excessive amounts. Therefore, investigating the photosynthetic response of microalgae to Zn stress is of great significance. In this study, we assessed the photosynthetic responses of neutrophilic and acidophilic sp.

FGL2 deficiency alleviates maternal inflammation-induced blood-brain barrier damage by blocking PI3K/NF-κB mediated endothelial oxidative stress.

Introduction: The impairment of blood-brain barrier (BBB) is one of the key contributors to maternal inflammation induced brain damage in offspring. Our previous studies showed Fibrinogen-like protein 2 (FGL2) deficiency alleviated maternal inflammation induced perinatal brain damage. However, its role in BBB remains undefined.

Stem Cells in the Myelodysplastic Syndromes.

The myelodysplastic syndromes (MDS) represent a group of clonal disorders characterized by ineffective hematopoiesis, resulting in peripheral cytopenias and frequent transformation to acute myeloid leukemia (AML). We and others have demonstrated that MDS arises in, and is propagated by malignant stem cells (MDS-SCs), that arise due to the sequential acquisition of genetic and epigenetic alterations in normal hematopoietic stem cells (HSCs). This review focuses on recent advancements in the cellular and molecular characterization of MDS-SCs, as well as their role in mediating MDS clinical outcomes.

Clinical and Functional Characterization of a Novel Mutation in Causing Nephrogenic Diabetes Insipidus in a Four-Generation Chinese Family.

Congenital nephrogenic diabetes insipidus (CNDI) is a rare inherited disease that is caused by mutations in (AVPR2) or (). Functional analysis of the mutated receptor is necessary to verify the impact of the mutation on receptor function and suggest some possible therapeutic strategies for specific functional defects. Family history and clinical information were collected.

Effect of high-fat diet for rats at different stages on glucose and lipid metabolism in offspring and related mechanisms.

Objectives: To study the effect of high-fat diet for maternal Sprague-Dawley rats at different stages on glucose and lipid metabolism in offspring and related mechanisms.

Methods: According to the diet before pregnancy and during pregnancy and lactation, maternal rats were randomly divided into four groups (=9 each): CC (control diet before pregnancy and during pregnancy and lactation), HC (high-fat diet before pregnancy and control diet during pregnancy and lactation), CH (control diet before pregnancy and high-fat diet during pregnancy and lactation), and HH (high-fat diet before pregnancy and during pregnancy and lactation), and all offspring rats were given control diet after weaning. The body weight of maternal rats was recorded before and during pregnancy.

Tumor Microenvironment-Derived R-spondins Enhance Antitumor Immunity to Suppress Tumor Growth and Sensitize for Immune Checkpoint Blockade Therapy.

Unlabelled: Natural killer (NK) cells and T cells are key effectors of antitumor immune responses and major targets of checkpoint inhibitors. In multiple cancer types, we find that the expression of Wnt signaling potentiator R-spondin genes (e.g.

Intrauterine inflammation induced white matter injury protection by fibrinogen-like protein 2 deficiency in perinatal mice.

Background: White matter injury (WMI) induced by intrauterine inflammation can cause adverse neurological outcomes. Fibrinogen-like protein 2 (FGL2)/fibroleukin is an important trigger of inflammatory responses and is involved in some cerebral diseases. However, the role of FGL2 in intrauterine inflammation-induced WMI remains unclear.

Decreased Circulating Levels of Asprosin in Obese Children.

Background: Circulating asprosin is a newly discovered adipokine that triggers the release of hepatic glucose stores and increases appetite. Asprosin levels are elevated in adult obese men as well as in mice, and reductions in asprosin protect against the hyperinsulinism associated with metabolic syndrome in mice with diet-induced obesity, which indicates a potential therapeutic role of asprosin in obesity and type 2 diabetes.

Objectives: Few data on asprosin in children are available, which is why this study aimed to assess concentrations of fasting asprosin, as well as its relationship to parameters of glucose and lipid metabolism, in children.

SETD2 mutations confer chemoresistance in acute myeloid leukemia partly through altered cell cycle checkpoints.

SETD2, an epigenetic tumor suppressor, is frequently mutated in MLL-rearranged (MLLr) leukemia and relapsed acute leukemia (AL). To clarify the impact of SETD2 mutations on chemotherapy sensitivity in MLLr leukemia, two loss-of-function (LOF) Setd2-mutant alleles (Setd2 or Setd2) were generated and introduced, respectively, to the Mll-Af9 knock-in leukemia mouse model. Both alleles cooperated with Mll-Af9 to accelerate leukemia development that resulted in resistance to standard Cytarabine-based chemotherapy.

Characterization of Wnt1-inducible Signaling Pathway Protein-1 in Obese Children and Adolescents.

Wnt1-inducible signaling pathway protein-1 (WISP1), a member of the CCN family, is increasingly being recognized as a potential target for obesity and type 2 diabetes mellitus. Recent studies have shown that WISP1 can regulate low-grade inflammation in obese mice, and circulating WISP1 levels are associated with obesity and type 2 diabetes mellitus in adults. Herein, we measured serum WISP1 levels in obese youth and explored its relationships with pro-inflammatory cytokine interleukin 18 (IL-18) and other metabolic indexes.

Characterization of fibroblast growth factor 1 in obese children and adolescents.

Background: Fibroblast growth factor 1 (FGF1) can regulate glucose and lipid metabolism in obese mice. Serum FGF1 has increased in type 2 diabetes mellitus adults and correlated with BMI. This study aimed to indicate conventional weight loss effects on FGF1 in obese children and adolescents.

The high NRF2 expression confers chemotherapy resistance partly through up-regulated DUSP1 in myelodysplastic syndromes.

Although cytarabine has been widely considered as one of the chemotherapy drugs for high-risk myelodysplastic syndromes (MDS), the overall response rate is only approximately 20-30%. Nuclear factor erythroid 2-related factor 2 (NRF2, also called NFE2L2) has been shown to play a pivotal role in preventing cancer cells from being affected by chemotherapy. However, it is not yet known whether NRF2 can be used as a prognostic biomarker in MDS, or whether elevated NRF2 levels are associated with cytarabine resistance.

Whole exome sequencing identifies novel mutations of epigenetic regulators in chemorefractory pediatric acute myeloid leukemia.

Genomic alterations underlying chemotherapy resistance remains poorly characterized in pediatric acute myeloid leukemia (AML). In this study, we used whole exome sequencing to identify gene mutations associated with chemo-resistance in 44 pediatric AML patients. We identified previously unreported mutations involving epigenetic regulators such as KDM5C, SRIT6, CHD4, and PRPF6 in pediatric AML patients.

Independent relationship between body mass index and LH peak value of GnRH stimulation test in ICPP girls: A cross-sectional study.

The effect of obesity on idiopathic central precocious puberty (ICPP) girls is still under discussion. The relationship between body mass index (BMI) and sexual hormone levels of gonadotropin-releasing hormone (GnRH) stimulation test in ICPP girls is controversial and the underlying mechanism is unclear. This study aims to further explore the independent effect of excess adiposity on peak luteinizing hormone (LH) level of stimulation test in ICPP girls and the role of other related factors.
