Assessment of self-perceived malocclusion and barriers to orthodontic treatment: A cross-sectional study.

Context: Malocclusion is a common dental issue that can lead to significant oral health problems. However, patient management and treatment options for malocclusion can vary, and there is a lack of information regarding self-perception and barriers to orthodontic care.

Aims: This study aimed to assess the self-perception of malocclusion and explore barriers to orthodontic care among residents of Bandar Saujana Putra in Klang Valley, Malaysia.

In vivo anti-tumor activity of Lignosus rhinocerus TM02® using a MCF7-xenograft NCr nude mice model.

Ethnopharmacological Relevance: Lignosus rhinocerus (Cooke) Ryvarden (also known as Tiger Milk mushroom, TMM), is a basidiomycete belonging to the Polyporaceae family. It has been documented to be used by traditional Chinese physicians and indigenous people in Southeast Asia to treat a variety of illnesses, such as gastritis, arthritis, and respiratory conditions, as well as to restore patients' physical well-being. TMM has also been used in folk medicine to treat cancer.

In silico analysis and characterization of medicinal mushroom cystathionine beta-synthase as an angiotensin converting enzyme (ACE) inhibitory protein.

Angiotensin-converting enzyme (ACE) regulates blood pressure and has been implicated in several conditions including lung injury, fibrosis and Alzheimer's disease. Medicinal mushroom Ganordema lucidum (Reishi) cystathionine beta-synthase (GlCBS) was previously reported to possess ACE inhibitory activities. However, the inhibitory mechanism of CBS protein remains unreported.

Immunomodulatory Properties of Water-Soluble Polysaccharides Extracted from the Fruiting Body of Chinese Caterpillar Mushroom, Ophiocordyceps sinensis Cultivar OCS02® (Ascomycetes).

Ophiocordyceps sinensis (=Cordyceps sinensis) has been known for its various medicinal properties, in particular immunomodulatory activities associated with its polysaccharides. In this study, the fruiting body of O. sinensis cultivar OCS02® was investigated for its chemical composition and monosaccharide profile.

Isolation and characterization of the thrombin-like enzyme from Cryptelytrops albolabris (white-lipped tree viper) venom.

A thrombin-like enzyme (termed albolabrase) was isolated in purified form from the venom of Cryptelytrops albolabris (white-lipped tree viper) using high performance anion ion exchange and gel filtration chromatography. The molecular mass of albolabrase was 33.7 kDa as determined by SDS-PAGE and 35.

Resistance against tumour necrosis factor α apoptosis by the cellular prion protein is cell-specific for oral, colon and kidney cancer cell lines.

Since the discovery of PrPC (cellular prion protein), most studies have focused on its role in neurodegenerative diseases, whereas its function outside the nervous system remains obscure. We investigated the ability of PrPC in resisting TNFα (tumour necrosis factor α) apoptosis in three PrPC-transiently transfected cancer cell lines, renal adenocarcinoma ACHN, oral squamous cell carcinoma HSC-2 and colon adenocarcinoma LS174T. PrPC-expressing ACHN and LS174T cells had higher viabilities compared with the mock-transfected cells, while the transient overexpression of PrPC had minimal overall effect on HSC-2 cells due to its high endogenous PrPC expression.

Resistance against apoptosis by the cellular prion protein is dependent on its glycosylation status in oral HSC-2 and colon LS 174T cancer cells.

Most studies have focused on the role of the cellular prion protein (PrP(C)) in neurodegenerative diseases, whereas the function of this ubiquitous protein outside the nervous system remains elusive. Therefore, the anti-apoptotic property of PrP(C) in oral squamous cell carcinoma (HSC-2) and colon adenocarcinoma (LS 174T) was evaluated in this study, by stable shRNA knockdown and overexpression, respectively. PrP(C) confers resistance against oxidative stress-apoptosis as indicated by MTT assay, Annexin V-FITC/PI and DCFH-DA staining, but this property is abolished upon N-glycosylation inhibition by tunicamycin.
