Drug-Loaded Hydrogel Microneedles for Sustainable Transdermal Delivery of Macromolecular Proteins.

Introduction: Poly(methyl vinyl ether co-maleic acid) (PMVE/MA) hydrogel microneedles (HMN) are investigated for transdermal delivery of macromolecular drugs owing to their biocompatibility and super-swelling properties. However, the drug delivery efficacy reduces with increasing molecular weight due to the entrapment within the HMN matrices. Furthermore, integrating external drug reservoirs extends the drug diffusion path and reduces the efficiency of drug permeation.

Potential CD34 signaling through phosphorylated-BAD in chemotherapy-resistant acute myeloid leukemia.

Acute myeloid leukemia (AML) constitutively express growth factors and cytokines for survival. Chemotherapy alters these signals to induce cell death. However, drug resistance in AML remains a major hindrance to successful treatment and early warning is unavailable.

In Vitro Antiatherothrombotic Effects of Extracts from L., L., and Benth.

Coronary artery disease is the leading cause of mortality and morbidity worldwide. The pathogenesis is mainly due to atherosclerosis, plaque rupture, and platelet thrombus formation. The main risk factors for coronary artery disease include obesity, hypercholesterolemia, smoking, diabetes, and high blood pressure.

Medicinal Herbals with Antiplatelet Properties Benefit in Coronary Atherothrombotic Diseases.

Coronary atherothrombotic diseases such as coronary artery disease, peripheral vascular disease, cerebrovascular disease, and heart failure are the serious concerns of the thrombus formed in blood vessels. Anticoagulant and antiplatelet drugs are the cornerstones of the management of these diseases. To prevent the recurrence of these diseases, double antiplatelet drugs such as aspirin and clopidogrel has been the standard management in most hospitals.

Anticoagulant Activity of Polyphenolic-Polysaccharides Isolated from Melastoma malabathricum L.

Melastoma malabathricum Linn. is a perennial traditional medicine plants that grows abundantly throughout Asian countries. In this study, M.

Adiponectin SNP45TG is associated with gestational diabetes mellitus.

Introduction: Diabetes and pregnancy can be associated in two ways: pregnancy that occurs in women who are already diabetic (diabetes of pre-gestational origin); and diabetes that occur in women who are already pregnant [gestational diabetes mellitus (GDM) (O'sullivan 1961)]. Patients with previous GDM history have higher risk of developing diabetes outside of pregnancy. Accumulating literature had suggested that adiponectin plays a role in the pathophysiology of this metabolic syndrome, and several of the common single nucleotide polymorphisms (SNP) in adiponectin gene have been identified in type 2 diabetes.

Bone marrow necrosis preceding infantile acute lymphoblastic leukaemia.

We report a case of bone marrow necrosis preceding infantile acute lymphoblastic leukaemia (ALL). Bone marrow necrosis is a rare antemortem event and has been known to be present in many conditions, notably in haematological malignancies like acute lymphoblastic leukaemia. This case was a 6-month-old Chinese boy who was referred to Hospital Universiti Kebangsaan Malaysia for further investigation of pancytopaenia, high-grade fever, bloody diarrhoea and petechial rashes for one week.
