Is serum hemoglobin level an independent prognostic factor for IgA nephropathy?: a systematic review and meta-analysis of observational cohort studies.

Background: Decreased serum hemoglobin (Hb) level is associated with Immunoglobulin A nephropathy (IgAN) progression. However, whether serum Hb level is an independent prognostic factor of IgAN remains controversial. Herein, we aimed to investigate the prognostic value of serum Hb level in IgAN.

Is hyperuricemia an independent prognostic factor for IgA nephropathy: a systematic review and meta-analysis of observational cohort studies.

Background: Hyperuricemia has been reported to be correlated with IgA nephropathy (IgAN). However, whether hyperuricemia or elevated serum uric acid (SUA) is an independent prognostic factor of IgAN remains unknown. Therefore, this systematic review and meta-analysis evaluated the prognostic value of hyperuricemia and elevated SUA in IgAN.

Aminoguanidine ameliorates ovariectomy-induced neuronal deficits in rats by inhibiting AGE-mediated Aβ production.

Advanced glycation end products (AGEs) have been reported to cause neurodegeneration, senile plaque formation and spatial learning and memory deficits. There is much evidence describing the beneficial effects of aminoguanidine (AG) on the central nervous system; AG is able to inhibit the receptor for AGEs and beta-amyloid (Aβ) deposition in the brain, thus preventing cognitive decline and neurodegeneration. In this study, we investigated whether AG protects against ovariectomy-induced neuronal deficits and Aβ deposition in rats.

Effect of Tang-Shen-Ning decoction on podocyte epithelial-esenchymal transformation via inhibiting Wnt/β-catenin pathway in diabetic mice.

Background: Diabetic nephropathy (DN) is the leading cause of end-stage renal disease (ESRD). Podocyte epithelial-esenchymal transformation (EMT) induced by the activated Wnt/β-catenin pathway plays a key role in DN. Tang-Shen-Ning (TSN), a Chinese herbal formula, has been shown to decrease proteinuria and protect the renal function in DN.

Effects of BSF on Podocyte Apoptosis via Regulating the ROS-Mediated PI3K/AKT Pathway in DN.

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease (ESRD). The ROS-mediated PI3K/AKT pathway plays a key role in podocyte apoptosis and DN progression. Our previous study demonstrated that Baoshenfang (BSF) can decrease proteinuria and attenuate podocyte injury.

Effect of Baoshenfang Formula on Podocyte Injury via Inhibiting the NOX-4/ROS/p38 Pathway in Diabetic Nephropathy.

Diabetic nephropathy (DN) is a serious kidney-related complication of type 1 and type 2 diabetes. The Chinese herbal formula Baoshenfang (BSF) shows therapeutic potential in attenuating oxidative stress and apoptosis in podocytes in DN. This study evaluated the effects of BSF on podocyte injury and and explored the possible involvement of the nicotinamide adenine dinucleotide phosphate-oxidase-4/reactive oxygen species- (NOX-4/ROS-) activated p38 pathway.

Medicine in Future and Advantages of Integrated Chinese and Western Medicine.

The history of medical development shows that oriental medicine, or traditional medicine, was born through medical practice during the times when science and technology were immature and underdeveloped, whereas with the development of science and technology, Western medicine, or modern medicine, was born through experimental analysis and research. With the development of medicine, the pros and cons of both medical systems become increasingly evident. How to integrate them and learn from each other will be the direction of future development of medicine.

Comparative analysis of proteomes between diabetic and normal human sperm: Insights into the effects of diabetes on male reproduction based on the regulation of mitochondria-related proteins.

This study sought to identify sources of the reduced fertility of men with type 2 diabetes mellitus. Significant reductions in semen volume, sperm concentration, and total sperm count were observed in diabetic individuals, while transmission electron microscopy revealed that the structure of mitochondria in the tail of sperm from diabetic patients was damaged. Proteins potentially associated with these sperm defects were identified using proteomics.

Discovery and Pre-Clinical Characterization of Third-Generation 4-H Heteroaryldihydropyrimidine (HAP) Analogues as Hepatitis B Virus (HBV) Capsid Inhibitors.

Described herein are the discovery and structure-activity relationship (SAR) studies of the third-generation 4-H heteroaryldihydropyrimidines (4-H HAPs) featuring the introduction of a C6 carboxyl group as novel HBV capsid inhibitors. This new series of 4-H HAPs showed improved anti-HBV activity and better drug-like properties compared to the first- and second-generation 4-H HAPs. X-ray crystallographic study of analogue 12 (HAP_R01) with Cp149 Y132A mutant hexamer clearly elucidated the role of C6 carboxyl group played for the increased binding affinity, which formed strong hydrogen bonding interactions with capsid protein and coordinated waters.

[Expression of EphA2 and EphrinA1 in human renal cell carcinoma and its relationship with angiogenesis].

Objective: To investigate the expression of EphA2 and EphrinA1 and its relationship with angiogenesis in renal cell carcinoma and its relevance to clinicopathologic features.

Methods: The expression of the EphA2 and EphrinA1 was detected by immunohistochemistry (IHC) in the tissues samples from 68 renal cell carcinomas and 24 normal kidneys, and quantitatively analyzed. The microvessel density (MVD) was determined by CD34 immunostaining of microvascular endothelial cells.

Sustained release subcutaneous delivery of BMS-686117, a GLP-1 receptor peptide agonist, via a zinc adduct.

BMS-686117 is an 11-mer GLP-1 receptor agonist with a short intrinsic pharmacokinetic half-life (t(1/2)) of approximately 2h. In order to develop an extended release formulation for once-daily (QD) subcutaneous administration, a non-covalently bonded Zn/BMS-686117 adduct with very low aqueous solubility was prepared through mixing zinc acetate and BMS-686117 solutions, followed by filtration or spray drying. At pH 6.

Preclinical safety, pharmacokinetics and antitumor efficacy profile of liposome-entrapped SN-38 formulation.

Background: SN-38, 7-ethyl-10-hydroxycamptothecin, is a biologically active metabolite of irinotecan. Its poor solubility restricted its development as an anticancer agent. We have developed an easy-to-use liposome-entrapped SN-38 (LE-SN38) and evaluated its toxicology, pharmacokinetics and antitumor efficacy profile.

Separation of liposome-entrapped mitoxantrone from nonliposomal mitoxantrone in plasma: pharmacokinetics in mice.

A method is described for quantification of the liposomal and nonliposomal forms of mitoxantrone (MTO) in mouse plasma after intravenous administration of liposome-entrapped MTO Easy-to-Use (LEM-ETU) formulation. This is based on the property of liposome-entrapped MTO (LEM) to pass through reversed-phase C(18) silica gel cartridges, while nonliposomal MTO or free MTO is retained with strong hydrophobicity and later is eluted with acidic methanol. Extraction of LEM and free MTO from plasma is performed in two steps.

A simple, rapid HPLC method for quantification of mitoxantrone in mouse plasma and tissue homogenates in the presence of a liposome entrapped mitoxantrone formulation (LEM-ETU) is described. Sample preparation is achieved by protein precipitation of 100 microl plasma or 200 microl tissue homogenate with an equal volume of methanol containing 0.5 M hydrochloric acid:acetonitrile (90:10, v/v).

Pharmacokinetics and metabolism of a COX-2 inhibitor, valdecoxib, in mice.

The pharmacokinetics and metabolism of valdecoxib, a potent cyclooxygenase-2 selective inhibitor, were investigated in mice. Valdecoxib was extensively metabolized after a single 5 mg/kg oral administration of [(14)C]valdecoxib and elimination of unchanged drug was minor (less than 1%) in male and female mice. The total mean percentage of administered radioactive dose recovered was 99.

Interaction between a single nucleotide polymorphism in the alcohol dehydrogenase 3 gene, alcohol consumption and oral cancer risk.

We investigated effects on oral cancer (OC) risk of an interaction between a single nucleotide polymorphism (SNP) in the alcohol dehydrogenase 3 (ADH3) gene and alcohol consumption levels using a hospital-based study of 93 cases and 99 controls conducted in Athens, Greece. This SNP affects ethanol metabolism in vitro and appeared to interact with alcohol consumption in a previous OC study. We also evaluated a SNP in CYP2E1, another gene involved in ethanol metabolism, reported to be associated with OC risk in a European population.
