Introduction: Inferior Vena Cava (IVC) is the largest vein of the body. It runs vertically upwards in the abdomen, behind the liver. Its course is very constant in relation to liver. However, the amount of liver parenchyma related to it can vary from person to person. The data regarding its course and relations may be very useful to radiologists and surgeons during surgical treatment procedures for Budd-Chiari syndrome, liver carcinoma, liver transplant, venous cannulations and many other clinical procedures.
Aim: Aim of this study was to document the incidence of straight and curved course of IVC in relation to liver and also to note the pattern in which the liver tissue was related to the IVC.
Materials And Methods: In the current study, 95 adult cadaveric livers were observed; specifically to study the course/direction of the hepatic segment of IVC in relation to the liver. The extent of liver tissue related to various aspects of IVC was also studied. The course of the IVC was classified as straight and curved; and the relationship of liver parenchyma to the IVC was classified into 6 categories. The data was expressed as percentage incidence.
Results: In 78.94% cases, the IVC had a straight course in relation to the liver; whereas in 21.06% cases, it had a left sided curve (concavity of the curve towards the caudate lobe) in its course. In 6.31% cases, IVC travelled in a tunnel, being encircled by the liver parenchyma all around; in 36.84% cases, it was covered by liver parenchyma on front and sides so that only posterior surface of IVC was visible; in 3.15% cases it was covered by liver tissue on front, sides and also partly on posterior aspect; in 50.52% of cases, its anterior surface, sides and left edge of the posterior surface was covered by liver tissue; and in 3.15% cases it was covered only from the front by the liver tissue.
Conclusion: The data being reported here might be useful for surgeons while planning and executing various hepatic surgeries and also to the radiologists in planning and performing venous cannulation and therapeutic procedures. Since in many livers, the curvature of IVC was associated with enlarged caudate lobe, the curved IVC could hint about the increase in the volume of caudate lobe or liver itself.

Background: The vicious cycle between depression and dementia increases the risk of Alzheimer's Disease (AD) pathogenesis and pathology. This study investigates therapeutic effectiveness versus side effects and the underlying mechanisms of intranasal dantrolene nanoparticles (IDNs) to treat depression behavior and memory loss in 5XFAD mice.
Method: 5XFAD and wild-type B6SJLF1/J mice were treated with IDNs (IDN, 5 mg/kg) in Ryanodex formulation for a duration of 12 weeks.

Background: The DL-3-n-butylphthalide (NBP), a multi-target neuroprotective drug, improving cognitive impairment in patient with vascular cognitive impairment has been confirmed. The efficacy of NBP in patients with cognitive impairment due to Alzheimer's disease (AD) remains unknown. This study aimed to evaluate the efficacy and safety of NBP in patients with mild cognitive impairment (MCI) due to AD though a clinical randomized controlled trail.

Background: Cyclin Y (CCNY) is a member of cyclin protein family inhibiting long-term synaptic plasticity, which is related to the learning and memory function in neuronal system. Recently, CCNY has been reported to associate with the cognitive deficits in Alzheimer's disease (AD).
Method: In this study, we discovered PFTAIRE peptide to diminish CCNY protein level and to ameliorate cognitive dysfunction in AD.
Background: The increased incidence of Alzheimer's disease (AD) rate represent an unmet medical need and thus critical for the development of novel molecular therapeutics. Recent work focusing on patients with apoE4 alleles has highlighted the association of brain cholesterol dysregulation with elevated pathological burden and neurodegeneration. These studies have highlighted the importance of the nuclear receptor Liver X receptor (LXR) for developing AD therapies.

Remyelination, of the myelin sheath by oligodendrocytes, is a process that may be impaired in neurodegenerative diseases. Depending on the severity of the disease, there occurs loss or partial damage of the myelin sheath surrounding the neuron leading to memory deficits.
