Correlation between serum heavy metals and the risk of oral squamous cell carcinoma and oral potentially malignant disorders.

Oral squamous cell carcinoma (OSCC) is a serious public health problem in various Asian countries, including Sri Lanka, and a combination of cultural practices, lifestyle factors, and genetic predispositions influences the incidence of these cancers. The examination of the connection between exposure to heavy metals and the probability of developing oral potentially malignant disorders (OPMD) and OSCC has been limited in its scope, and the overall consequences of such exposure remain largely unknown. This study aims to clarify the link between serum levels of heavy metals and the risk of OSCC and OPMD.

Validation of the Sinhala Version of the Addenbrooke's Cognitive Examination-Revised for the Detection of Dementia in Sri Lanka: Comparison with the Mini-Mental Status Examination and the Montreal Cognitive Assessment.

Background: Sri Lanka is a rapidly aging country, where dementia prevalence will increase significantly in the future. Thus, inexpensive and sensitive cognitive screening tools are crucial.

Objectives: To assess the reliability, validity, and diagnostic accuracy of the Sinhalese version of the Addenbrooke's Cognitive Examination-Revised (ACE-R s).

Contrast Therapy and Heat Therapy in Subacute Stage of Grade I and II Lateral Ankle Sprains.

Unlabelled: Objective This study was conducted to determine the most effective thermal modality; heat or contrast therapy-in reducing pain, reducing swelling, and increasing range of movement (ROM) of the grade I and II lateral ankle sprain in the prechronic stage of the subacute phase. Design Randomized control trail. Methods One hundred and fifteen participants of both genders who were diagnosed as having grade I or II lateral ankle sprain were randomly assigned to the study on the fifth day of injury.

Crystalline state photochromism of 3-furylfulgides: impact of size and bond flexibility of the non-aromatic alkylidene group.

3-Furylfulgides are photochromic compounds showing high thermal stability in their closed forms. However, their photochromic properties in the solid state should be improved further to fabricate molecular devices. Understanding how the size and the flexibility of the non-aromatic alkylidene moiety alter the crystalline state photochromic properties is also important here, as the alkylidene group is directly involved in the photochromic ring closing and opening reactions.
