Smouldering Myeloma: Chasing a Hyperviscous Sample.

Serum hyperviscosity is a rare laboratory finding. Amongst several causes of serum hyperviscosity, malignant disorders are quite common. Monoclonal gammopathy is a family of disorders in which monoclonal gammopathy of unknown significance (MGUS) and smoldering myeloma are the asymptomatic variants whereas multiple myeloma is the malignant variant showing different signs and symptoms related to bone lesions, renal failure and anemia.

Association of Triglyceride-Glucose Index (TyG index) with HbA1c and Insulin Resistance in Type 2 Diabetes Mellitus.

The aim of this study was to assess the association of triglyceride-glucose (TyG) index with glycated haemoglobin (HbA1c) and insulin resistance in type 2 diabetes mellitus (T2DM). A total of 140 patients with T2DM were included in this cross-sectional study and divided into two groups according to their HbA1c levels: participants with HbA1c <7.0% (n=75) and those with HbA1c >7.

Testing the Psychometric Properties of the Postpartum Sleep Quality Scale in Turkish Women.

Background: Postpartum sleeplessness has been observed to be an important health problem in Turkey. However, no scale is currently available to evaluate quality of sleep in Turkish postpartum women.

Purpose: The aim of this study was to test the validity and reliability of the Turkish Postpartum Sleep Quality Scale (T-PSQS).

Bortezomib induces apoptosis by interacting with JAK/STAT pathway in K562 leukemic cells.

In the current study, we aimed to identify the cytotoxic and apoptotic effects of bortezomib (BOR) on human K562 chronic myelogenous leukemia cells and to evaluate the potential roles of Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway members STAT3, STAT5, and JAK2 on BOR-induced cell death of leukemic cells. Cell viability was assessed via trypan blue dye exclusion test, and cytotoxicity of the BOR-treated cells was conducted by 2,3-bis(2-methoxy-4-nitro-5-sulphophenyl)-2H-tetrazolium-5-carboxanilide inner salt (XTT) assay. The relative messenger RNA (mRNA) expression levels of STAT3, STAT5A, STAT5B, and JAK2 were analyzed by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR).

STAT pathway in the regulation of zoledronic acid-induced apoptosis in chronic myeloid leukemia cells.

In this study, we aimed to evaluate the cytotoxic and apoptotic effects of zoledronic acid on K562 chronic myeloid leukemia (CML) cells and to examine the roles of STAT genes on zoledronic acid-induced apoptosis. The results showed that zoledronic acid decreased proliferation, and induced apoptosis in K562 cells in a dose- and time-dependent manner. mRNA and protein levels of STAT3, -5A and -5B genes were significantly reduced in zoledronic acid-treated K562 cells.
