Type 2 diabetes (T2D) is a chronic metabolic disorder caused by defective insulin signaling, insulin resistance, and impairment of insulin secretion. Autophagy is a conserved lysosomal-dependent catabolic cellular pathway involved in the pathogenesis of T2D and its complications. Basal autophagy regulates pancreatic β-cell function by enhancing insulin release and peripheral insulin sensitivity.

Article Synopsis
  • Parkinson's disease (PD) is caused by the degeneration of dopaminergic neurons, leading to various motor and non-motor symptoms, with GABA neurotransmission playing a key protective role against this degeneration.
  • Sleep disorders in PD, such as insomnia and fragmented sleep, are linked to reduced GABA levels, which can further exacerbate cognitive dysfunction and overall PD symptoms.
  • The review highlights the need for more prospective studies to better understand GABA's role in PD neuropathology, especially concerning sleep disorders, and suggests investigating GABA agonists as a potential treatment avenue.

The prognosis of metastatic lung melanoma (MLM) has been reported to be poor. An increasing number of studies have reported the function of several immune cells in cancer regression. Although the function of mediastinal fat-associated lymphoid clusters (MFALCs) in the progression of inflammatory lung lesions has been previously reported, the association between MLM progression and MFALCs development has remained unexplored.

Background: Polyinosinic-polycytidylic acid (pIC) is a synthetic analog of double-stranded RNA. It is used as a synthetic adjuvant to induce an adaptive immune response. However, the effect of pIC on the development of mediastinal fat-associated lymphoid clusters (MFALCs) that regulate intrathoracic hemostasis has remained unidentified.

Parkinson's disease (PD) is one of the most common degenerative brain disorders caused by the loss of dopaminergic neurons in the substantia nigra (SN). Lewy bodies and -synuclein accumulation in the SN are hallmarks of the neuropathology of PD. Due to lifestyle changes and prolonged L-dopa administration, patients with PD frequently have vitamin deficiencies, especially folate, vitamin B6, and vitamin B12.

Hepatocellular carcinoma (HCC) is a malignant tumor with limited treatment options. Given this fact, it may be important to develop new molecular targeted therapies from natural products, especially those which are primary sources of effective anticancer drugs with distinct mechanisms. Moreover, the complementary use of traditional herbs or fruit may increase the possibility of finding curative options for cancer.

Introduction: Parathormone (PTH) and phosphorus, which are considered as uremic toxins, are associated with reduced red cell survival, yet with unproven mechanism. We aimed to assess the relation between PTH and phosphorus levels and eryptosis in patients with CKD5d treated by hemodialysis.

Methods: In a cohort of 85 patients with CKD5d treated by conventional hemodialysis, the percent of annexin V-binding RBCs was assessed by flow cytometry to indicate the percent of eryptotic RBCs.

The aim of this study was to assess the efficacy and safety of two protocols for retreatment of a cohort of Egyptian patients with chronic hepatitis C (CHC) who relapsed after NS5A inhibitor-based therapy. We conducted a prospective cohort study to assess the safety and efficacy of 12 weeks' retreatment with either combination of sofosbuvir/daclatasvir/simeprevir plus ribavirin (SOF/DCV/SMV/RBV, n = 45) or sofosbuvir/ombitasvir/paritaprevir/ritonavir plus ribavirin (SOF/OBV/PTV/r/RBV, n = 163) in patients who had previously failed NS5A inhibitors-based regimens. The primary end point was SVR 12 weeks after the end of treatment (SVR12).

Article Synopsis
  • The study investigates the phenomenon of occult hepatitis C infection (OCI) in Egyptian patients who achieved sustained virologic response (SVR) after treatment with direct-acting antiviral agents (DAAs).
  • A total of 150 patients with chronic hepatitis C were tested for HCV RNA in their blood cells, revealing that 11.33% of them had positive results despite showing no active infection in serum.
  • The research suggests that dual testing for HCV RNA in both serum and blood cells is essential to accurately assess the presence of OCI post-treatment, particularly after DAA therapy.
