Total organic carbon (TOC), black carbon (BC), total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) were determined in 73 surface (0-2 cm) and subsurface (5-20 cm) soil samples taken from a 142 km2 area in Central London, UK. Soils were assessed to provide a baseline chemistry for site owners, developers, occupiers and regulators involved in understanding the potential risk to human health and the environment. TOC range was 1.75-11.85 % (mean 5.82 %), BC 3.7 [...]

Prefabricated zirconia crowns (ZRCs) require a passive fit and more reduction than stainless steel crowns (SSC). To determine the mean and maximum reduction depths in the mesial-buccal and occlusal areas for three ZRC brands and one SSC in posterior primary typodont molars and to compare reduction depths to existing literature to determine the preparation’s proximity to pulpal tissue. Four primary maxillary and mandibular typodont teeth (J and S) were prepared according to the manufacturers’ guidelines for three ZR [...]

The complete spectrum of neuropsychiatric effects of SARS-CoV-2 acute respiratory distress syndrome has yet to be fully appreciated, particularly in intubated patients. Manifestations including delirium and catatonia need to be considered in intubated COVID-19 patients. Medications known to exhibit neuroprotective effects, like valproate, can assist in agitation related to sedative withdrawal during extubation. This case series reports on the management of agitation, delirium, and catatonia in COVID-19 patients dur [...]

Using musical scales in a therapeutic key is one of the fundamental music therapy techniques of the Yoga of Sound (Nāda Yoga). The practice consists of singing particular sound formulas (scales), which are devised on a logical mathematical basis formed by specific musical intervals. These scales can bring to the surface, in a clear (objective), recognizable, and predictable way, psycho-emotional states and transform the blocked emotional energies. These blocked emotional energies are caused by repeated emotional st [...]

Feline cancers have not been studied as extensively as canine cancers, though they may offer similar advantages, with cats being immunocompetent animals subject to similar conditions as their human counterparts. The most common feline cancers include lymphoma, squamous cell carcinoma, sarcoma, and mammary tumors, though mast cell tumors were also investigated in this review. As the pathogenesis of many feline cancers remains unclear, this study seeks to elucidate some molecular mechanisms behind feline cancers. Fel [...]

We studied how GC death in glaucoma related to the intraocular pressure (IOP), eyeball volume (VS) and elasticity (volumetric KS and tensile ES), and eyeball volume-pressure relation. Glaucomatous GC loss was studied in DBA/2J (D2) mice with wild-type mice as controls. GCs were retrogradely identified and observed with a confocal microscope. The elasticity calculation was also done on published data from patients treated by a gas bubble injection in the vitreous cavity. The GC population in D2 mice (1.5- to 14-mont [...]

Photobiomodulation (PBM) is an accurate term for an effective and important application of light in medicine (such as in photomedicine). Three review articles of authors from the International Society of Medical Laser Applications (ISLA-Transcontinental) on the topic of PBM with a total of 116 printed pages, published in one renowned journal of molecular sciences with an impact factor of 13.668, are presented in the current review. The main topics are PBM, probiotics, curcumin, and arthritis. PBM can modulate cellu [...]

Deep-Brain Stimulation (DBS) is an important treatment option for the management of Parkinson’s disease (PD) and is a common symptomatic treatment. However, an increasing number of studies have examined the biological processes to assess if DBS can also modify the natural history of PD by acting on its pathophysiological mechanisms. Relevant literature published up to November 2020 was systematically searched on databases such as PubMed, ISI Web of Knowledge, Academic Search Index, and Science Citation Index. The f [...]

Glioblastoma multiforme (GBM) is an extremely malignant type of primary brain tumor that exhibits a high mortality rate. Current standard therapy involves surgery followed by radiation and treatment with the DNA-alkylating agent, temozolomide (TMZ). While TMZ treatment can extend post-operative survival, most patients develop resistance to TMZ which leads to a significant increase in mortality. At the molecular level, TMZ produces a variety of different DNA lesions including N7-methylguanine, N3-methyladenine, and [...]

Oesophageal cancer is the ninth most common cancer and the sixth most common cause of cancer deaths worldwide [1]. Over the past number of years, due to earlier diagnosis and better treatment, we are seeing improvements in the survival rates of oesophageal cancer, with more patients living longer post-esophagectomy surgery. Unintentional weight loss is a common unintended feature seen in patients post-esophagectomy done with curative intent. Many recent studies have demonstrated the links between the pathophysiolog [...]
