Low back pain is widely recognized as one of the most prevalent pathologies in the developed world. In the United States, low back pain is the most common health problem for adults under the age of 50, resulting in significant societal and personal costs. While the causes of low back pain are myriad, it has been significantly associated with intervertebral disc (IVD) degeneration. Current first...

Intervertebral disc (IVD) degeneration is a multifactorial process that is influenced by contributions from genetic predisposition, the aging phenomenon, lifestyle conditions, biomechanical loading and activities, and other health factors (such as diabetes). Attempts to decelerate disc degeneration using various techniques have been reported. However, to date, there has been no proven technique...

Neural stem and progenitor cells can be expanded under growth factor stimulation in vitro. It is likely that different mitogens and different culturing techniques selectively expand specific subclasses of cells, but this selection has not been well studied. We have expanded human cells isolated from the lateral ganglionic eminence (LGE) of a 10-week-old embryo in the presence of serum and epide...

A homemade CO2-laser photoacoustic spectrometer has been used for monitoring CO2 in gas samples extracted under vacuum from the wood of old spruce disc tree-rings for a ∼60 year series. The experimental results show that (1) the CO2 concentration exhibits annual trends correlated with an increase in atmospheric CO2 in a number of cases; (2) at the time when the annual CO2 trend changes from pos...

Multipotent neuroblasts (NBs) are produced throughout life by neural stem cells in the forebrain subventricular zone (SVZ), and are able to travel long distances to the olfactory bulb. On arrival in the bulb, migrating NBs normally replace olfactory neurons, raising interest in their potential for novel cell replacement therapies in various disease conditions. An understanding of the migratory ...

Objective (s): Mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease.Materials and Methods:Everydiscs containing 70 mg stem bark extract of Ziziphus jujuba were formulated  by using Carbopol 934, PVP k30 and gelatin as polymers. Discs were made by granulation  and direct compression. Discs were standardized based on the total phenol.  Properties such as in vi...

Alopecia areata (AA) is an organ-specific autoimmune disease resulting from the attack of hair follicle (HF) autoantigens through a T-cell-mediated mechanism. If there depletion mTregs in HFs, especially around both bulge and bulb, it could be related to patchy loss scalp may affect AA pathogenesis. Here, we investigated possible contributory role tissue-resident memory T cells (TRMs) regulator...
