BACKGROUND: Adjacent segment disease (ASD) is a common complication after lumbar decompression and fusion surgery. Traditional revision-surgery, including posterior lumbar decompression and posterolateral fusion (PLF) or interbody fusion (PLIF) is traumatic. The percutaneous endoscopic transforaminal procedure (PE-TF) has been widely used in patients with lumbar disc disease. However, there are no reports about using PE-TF procedure to treat ASD in the current literature. OBJECTIVE: To compare the clinical outcomes between PE-TF and PLF for single-level ASD after PLF or PLIF...

Botulinum toxin, also called the "miracle toxin," is a neurotoxin produced by the bacteria Clostridium botulinum. It is known to block nerve signals that contract muscles resulting in a temporary paralysis of the muscles. Toxins type A and B have been extensively studied and utilized in the realm of beauty and cosmetology. Initially, the toxin gained popularity as a disease-causing "poison". It was only later that it found its way to becoming a must have in modern aesthetic practice. Today, this wonder toxin has proven to be an apt and convenient option in the field of anti-aging medicine...

Herbs and spices have been used for food and medicinal purposes for centuries - the first recorded evidence of their use dates back to 1500BC and the Ebers Papyrus, which mentioned spices such as anise, mustard, saffron, cinnamon, and cassia. Now, in the 21st century, a variety of secondary compounds produced by plants are used in many fields of industry, such as food production (to improve taste, to provide vitamins and macro- and microelements, and also to inhibit food spoilage caused by foodborne bacteria), in medicine (in the treatment of various diseases; in chemoprevention and cancer therapy; as a source of natural antimicrobials for the treatment of infectious disease), and in pharmacology and cosmetology (in dietary supplements, and as a result of the demand for preservative-free cosmetics, to reduce the risk of methylparaben allergies)...

Interest in elasticity estimation for thin layers is increasing because of the various potential applications, including dermatology and cosmetology. In this context, we propose a dedicated elastographic system using 1-D high-frequency transient elastography (HF-TE) to estimate the 1-D Young's modulus through the dermis and hypodermis, which are the two human skin layers of interest in this study. An experimental validation of the HF-TE method was first carried out on two homogeneous tissue-mimicking hard and soft phantoms...

Ligninolytic extracellular enzymes, including lignin peroxidase, are topical owing to their high redox potential and prospective industrial applications. The prospective applications of lignin peroxidase span through sectors such as biorefinery, textile, energy, bioremediation, cosmetology, and dermatology industries. The litany of potentials attributed to lignin peroxidase is occasioned by its versatility in the degradation of xenobiotics and compounds with both phenolic and non-phenolic constituents. Over the years, ligninolytic enzymes have been studied however; research on lignin peroxidase seems to have been lagging when compared to other ligninolytic enzymes which are extracellular in nature including laccase and manganese peroxidase...

Menthol's various biological properties render it a useful component for medical and cosmetological applications, while its three centers of asymmetry mean that it can be used in a range of organic reactions. Menthol-substituted ionic liquids (ILs) have been found to exhibit promising antimicrobial and antielectrostatic properties, as well as being useful in organic catalysis and biochemical studies. However, so far, a force field designed and validated specifically for the menthol molecule has not been constructed...

BACKGROUND: Measuring the thickness of the stratum corneum (SC) in vivo is often required in pharmacological, dermatological, and cosmetological studies. Reflectance confocal microscopy (RCM) offers a non-invasive imaging-based approach. However, RCM-based measurements currently rely on purely visual analysis of images, which is time-consuming and suffers from inter-user subjectivity. METHODS: We developed an unsupervised segmentation algorithm that can automatically delineate the SC layer in stacks of RCM images of human skin...

Chemical relaxers are products marketed to straighten the hair and have been principally used by African Americans since the early twentieth century. They contain alkaline agents that break and reform hydrogen and disulfide bonds, leaving hair permanently straightened. Relaxers cause loss of tensile strength and increased fragility of the hair shaft that lead to increased risk of hair breakage and thinning. When used improperly, they can also cause local irritant contact dermatitis and chemical burns to the scalp and hairline that can potentially lead to a scarring alopecia...

Among many antioxidants that are used for the repairing of oxidative stress induced skin damages, we identified the enriched astaxanthin extract (EAE) from Haematococcus pluvialis as a viable ingredient. EAE was extracted from the red microalgae through supercritical fluid carbon dioxide extraction. To compare the effectiveness, EAE wastreated on human dermal fibroblasts with other components, phorbol 12-myristate 13-acetate (PMA), and doxycycline. With sirius red staining and quantitative real-time polymerase chain reaction (qRT-PCR), we found that PMA decreased the collagen concentration and production while overall the addition of doxycycline and EAE increased the collagen concentration in a trial experiments...

Dear Editor, Ultraviolet (UV) radiation is a well-known physical hazard responsible for photoaging, photoallergic, and phototoxic reactions as well as carcinogenesis, including life-threatening melanomas (1,2). Overexposure to both natural and artificial UV radiation is a public health concern. 30% of cancers diagnosed worldwide are skin cancers. Approximately three million non-melanoma skin cancers and 132 000 new cases of melanomas are diagnosed globally each year (3). Sunburns, especially in childhood, are a very important risk factor for melanomas...

Nose is the most prominent part of the mid-face and has important physiological, aesthetic and psychological functions. Skin diseases on the nose are commonly seen by dermatologists, otorhinolaryngologists, and plastic surgeons. Because of its exposed, highly visible localization, lesions on the skin of the nose are often noticed by patients themselves, typically very early in the course of the disease. Similarly, the dermatological lexicon is well known with descriptive terminologies, synonyms, acronyms, eponyms, toponyms, misnomers...
