Article Synopsis
  • The study analyzed various cold-pressed edible oils from Macedonia, focusing on their bioactive compounds and antioxidant activity evaluated through three different assays.
  • Apricot kernel oils were high in monounsaturated oleic acid, while paprika seed oil was rich in polyunsaturated linoleic acid, and γ-tocopherol was most abundant in sesame seed oil.
  • Different assays proved most effective for specific oils, with DPPH being best for sunflower oil, TEAC for sesame and paprika seed oils, and β-carotene for oils from highly pigmented plants.

Background: For over 100 years white-light cystoscopy has remained the gold-standard technique for the detection of bladder cancer (BCa). Some limitations in the detection of flat lesions (CIS), the differentiation between inflammation and malignancy, the inaccurate determination of the tumor margin status as well as the tumor depth, have led to a variety of technological improvements. The aim of this review is to evaluate the impact of these improvements in the diagnosis of BCa and their effectiveness in clinical practice.

The Effects of One Amino Acid Substitutions at the C-Terminal Region of Thermostable L2 Lipase by Computational and Experimental Approach.

Mol Biotechnol

January 2018

Faculty of Biotechnology and Biomolecular Sciences, Enzyme and Microbial Technology Research Centre, University Putra Malaysia (UPM), 43400, Serdang, Selangor Darul Ehsan, Malaysia.

The substitutions of the amino acid at the predetermined critical point at the C-terminal of L2 lipase may increase its thermostability and enzymatic activity, or even otherwise speed up the unfolding of the protein structure. The C-terminal of most proteins is often flexible and disordered. However, some protein functions are directly related to flexibility and play significant role in enzyme reaction.

Tuberculosis (TB) is a bacterial disease responsible for millions of infections and preventable deaths each year. Its treatment is complicated by patients' noncompliance due to dosing frequency, lengthy treatment, and adverse side effects associated with current chemotherapy. However, no modifications to the half-a-century old standard chemotherapy have been made based on a nanoformulation strategy to improve pharmacokinetic efficacy.

Topological properties of some sequences defined over 2-normed spaces.

Springerplus

November 2016

Department of Mathematics and Institute for Mathematical Research, University Putra Malaysia (UPM), 43400 Serdang, Selangor Malaysia.

The paper investigates some classes of real number sequences over 2-normed spaces defined by means of Orlicz functions, a bounded sequence of strictly positive real numbers, a multiplier and a normal paranormed sequence space. Relevant properties of such classes have been investigated. Moreover, relationships among different such classes of sequences have also been studied under various parameters and conditions.

Although there is evidence that hexaminolevulinate (HAL)-based transurethral bladder tumor resection (TURBT) improves the detection of Ta-T1 non-muscle-invasive bladder cancer (NMIBC) as well as carcinoma there is uncertainty about its beneficial effects on progression. A systematic literature search was conducted according to the PRISMA statement to identify studies reporting on HAL- vs. white-light (WL-) based TUR-BT in non-muscle invasive bladder cancer between 2000 and 2016.

Although intravesical instillation of Bacille-Calmette-Guerin (BCG) immunotherapy was approved many decades ago as a first line therapy for intermediate to high-risk non-muscle invasive bladder cancer, its long-term efficacy is still arguable as a proportion of up to 30-40% of patients will develop recurrence or progression of their disease. Based on currently available data on the clinical application of checkpoint inhibitors in solid tumors, the mucosa-associated lymphoid tissue seems to be a main target for anti-CTLA-4 antibodies. In this manuscript we hypothesize that the combination of anti-CTLA-4 therapy with BCG might enhance the immune activity in the bladder submucosal tissue, and subsequently, improve oncological outcomes of NMIBC.

Department of Orthopedics and Traumatology, University Kebangsaan Malaysia Medical Centre (UKMMC), University Kebangsaan Malaysia (National University of Malaysia), Jalan Ya'acob Latif, Bandar Tun. Razak, 56000 Cheras, Kuala Lumpur, Malaysia.

The application of bone substitutes and cements has a long standing history in augmenting fractures as a complement to routine fracture fixation techniques. Nevertheless, such use is almost always in conjunction with definite means of fracture fixation such as intramedullary pins or bone plates. The idea of using biomaterials as the primary fixation bears the possibility of simultaneous fixation and bone enhancement.
