Back pain is one of the main global health problems with a high level of prevalence and patients’ disability. In most cases, it is associated with degenerative spine damage (degenerative disc disease), dorsopathy, discopathy (M51 and M53 according to the International Classification of Diseases, 10th revision), affecting all levels of the intervertebral disc (IVD) (cytological, chemical and biochemical) as a whole as well as biological molecules that regulate homeostasis of the disc intercellular substance (growth factors, pro-inflammatory cytokines, enzymes).

Background: One of skin diseases that is frequently taking attention among teenagers and young adults is acne or in medical term called acne vulgaris. Acne treatment can be treated by repairing follicular abnormalities, decreasing sebum production, decreasing the number of Propionibacterium acnes colonies and reducing inflammation of the skin. The bacterial population of Propionibacterium acnes can be reduced by giving an antibacterial substance such as erythromycin, clindamycin and benzoyl peroxide.

Due to the importance of the intervertebral disc in the mechanical behavior of the human spine, special attention has been paid to it during the development of finite element models of the human spine. The mechanical behavior of the intervertebral disc is nonlinear, heterogeneous, and anisotropic and, due to the low permeability, is usually represented as a hyperelastic model. The intervertebral disc is composed of the nucleus pulposus, the endplates, and the annulus fibrosus. The annulus fibrosus is modeled as a hyperelastic matrix reinforced with several fiber families, and researchers have

Abstract:

Chronic low back pain is a disease that most often affects people between 45 and 64 years. The incidence of low back pain goes from 60 to 90% and the annual incidence is 5%. Often low back pain is accompanied or replaced by an irradiated lower limb pain, configuring the symptomatology of lumboradiculalgia, whose most frequent cause is the disco-radicular conflict. The cause of the onset of pain, even excruciating, in cases of radicular compression of disc origin is not yet clear. Low back pain of disc origin is thought to be caused by direct mechanical compression factors; by indirect mechanic

Abstract:

Cyanidation remains the predominant technology for the dissolution of gold from mineral raw materials. Environmental and technological disadvantages in the use of cyanides are the cause of the development of alternative systems, which include reagent-oxidant and reagent-complexant. A special place is occupied by the solvents, in which the formation of heteroligand complexes of gold is possible. Thus due to the formation of more durable compounds the rate of dissolution of the metal increases. In this work, as the ligands the thiourea and the ions of thiosulfate in the form of sodium salt were

This study investigates whether the measurement of glucocorticoid metabolites (GCMs) in feces is a useful method for the noninvasive evaluation of stress in the endangered Tsushima leopard cats (Prionailurus bengalensis euptilurus). Feces were collected from six seemingly healthy and five diseased (renal dysfunction, adrenal tumor, hernia, feline immunodeficiency virus (FIV), feline leukemia virus (FeLV)) Tsushima leopard cats in captivity. Fecal GCMs were measured by enzyme immunoassay (EIA) for cortisol. Individuals that experienced a physical examination under anesthesia showed increased fe

Abstract:

Abstract OBJECTIVE Minimally invasive microdiscectomies are commonly being performed for disc herniations. Although inadvertent dural tears are not common, they do occur. Present management of many dural tears includes fibrin glue or other adhesive substances over the dura, tight closure of the fascia and skin, and possibly bedrest. Because these surgeries are usually performed through a small tube, a primary dural repair can be prohibitively difficult. One reason for the difficulty in a primary closure is that the small tube limits the use of proper opening and closing of standard dural repai

This paper reviews progress made over the last decade with the shrinking object approach to the kinetics of batch dissolution. It demonstrates how the O’Connor–Greenberg equation leads to three dissolutions: those that remain well undersaturated, those that saturate with a great excess of solid left-over, and those in the middle ground where saturation is approached or attained, but where much of the solid originally added dissolves. The equations that describe these conditions are discussed, alongside sample results that validate their use with test substances, for example, salts, sucrose, si
