Diet is one of the major factors that can exert a majorly influence on colorectal cancer risk. This systematic review aimed to find correlations between various diet types, food or nutrients and colorectal cancer risk among Asian populations. Search limitations include dAsian populations residing in Asia, being published from the year 2008 till present, and written in the English language. A total of 16 articles were included in this systematic review. We found that red meats, processed meats, preserved foods, saturated/animal fats, cholesterol, high sugar foods, spicy foods, tubers or refined carbohydrates have been found by most studies to have a positive association with colorectal cancer risk. Inversely, calcium/dairy foods, vitamin D, general vegetable/fruit/fiber consumption, cruciferous vegetables, soy bean/soy products, selenium, vitamins C,E and B12, lycophene, alpha-carotene, beta-carotene, folic acid and many other vitamins and minerals play a protective role against colorectal cancer risk. Associations of fish and seafood consumption with colorectal cancer risk are still inconclusive due to many varying findings, and require further more detailed studies to pinpoint the actual correlation. There is either a positive or no association for total meat consumption or white meats, however their influence is not as strong as with red and processed meats.

Polysaccharides from different sources have found their applications in the wound care for their inherent abilitiesof gelling, biocompatibility, biodegradability, and antibacterial activity. Considering the low cost, ease of processing,abundance in nature and therapeutic benefits of the polysaccharides we developed psyllium, alginate and chitosan (PAC)composite fibers and modelled their physical properties namely; tenacity, linear density and absorption in both distilled waterand saline solution; using Box-Behnken (BB) technique of Response Surface Methodology (RSM). The PAC fibers wereproduced using an in house developed wet spinning module; briefly the dope solutions containing psyllium and alginate wereextruded into a hydrolyzed chitosan and CaCl2. The produced fibers were acetone washed to remove the polar solvent; in thiscase water; and later dried in air. The present work aimed at the development of statistical models for physical properties:linear density, tenacity, antibacterial efficacy and liquid absorption; of the composite PAC fibers. The factors underconsideration were the raw material concentration namely; alginate and psyllium in dope solution and calcium chloride(CaCl2) and hydrolysed chitosan in the coagulation bath. The experimental work was designed and analyzed using Minitab®17 statistical software. Regression models using the under consideration factors were successfully developed.

Face recognition is considered a complex biometrics in the field of image processing mainly due to the constraints imposed by variation in the appearance of facial images. These variations in appearance are affected by differences in expressions and/or occlusions (sunglasses, scarf etc.). This paper discusses incremental Kernel Fisher Discriminate Analysis on sub-classes for dealing with partial occlusions and variant expressions. This framework focuses on the division of classes into fixed size sub-classes for effective feature extraction. For this purpose, it modifies the traditional Linear Discriminant Analysis into incremental approach in the kernel space. Experiments are performed on AR, ORL, Yale B and MIT-CBCL face databases. The results show a significant improvement in face recognition.

Breast cancer is the most common cancer among women in Malaysia. Therefore, it is highly important for the public to be educated on breast cancer and to know the steps to detect it early on. Healthcare providers are in the prime position to provide such education to the public due to their high knowledge regarding health and their roles in healthcare. The present systematic review involved studies conducted in recent years to analyze the knowledge, attitudes and behavior of Malaysian healthcare providers regarding breast cancer, in attempts to obtain an overall picture of how well equipped our healthcare providers are to provide optimal breast cancer education, and to see their perceptions and actual involvement in said education. The systematic review was conducted via a primary search of various databases and journal websites, and a secondary search of references used by eligible studies. Criteria for eligibility included being published from the year 2008 till present, being conducted in Malaysia, and being written in the English language. A total of two studies were eligible for this review. Findings show that Malaysian future and current healthcare providers have moderate knowledge on breast cancer, have a positive towards involvement of breast cancer education, but have poor actual involvement.

The electronic and the magnetic properties of Cr-doped wurtzite cadmium sulfide (Cd1−xCrxS) at different concentrations (x = 12.5% and 6.25%) are investigated in the frame work of the generalized gradient approximation (GGA), its extension through on-site Hubbard U interactions (GGA+U), and the Tran Blaha modified Becke-Johnson (TB-mBJ) potential. The ferromagnetic exchange interactions between Cr-Cr atoms via S atoms are studied. The magnetic moments on these atoms are studied in detail by using different charge analysis techniques. The p-d hybridization reduces the local magnetic moment on Cr from its free space charge value and produces a small local magnetic moment on the nonmagnetic Cd and S host sites. Cr-doped CdS provides a half-metallic semiconductor.

Purpose: This study is aimed at investigating whether inpatient complications and surgical site infections (SSIs) occurred more commonly in patients undergoing total knee arthroplasty (TKA) during the summer season. Materials and Methods: A total of 725 patients who underwent unilateral or bilateral TKA were included in this study. A total of 241 patients (33.2%) underwent TKA between May and August. Our outcomes of interest were the incidence of postoperative complications and length of stay. Results: May–August surgeries were associated with a higher risk of postoperative inpatient complications (p=0.003). May–August surgeries (odds ratio [OR], 2.13; 95% confidence interval [CI], 1.18 to 3.85), postoperative transfusion (OR, 2.46; 95% CI, 1.43 to 4.26), postoperative special care unit stay (OR, 4.68; 95% CI, 1.99 to 11.0) and chronic kidney disease (OR, 3.27; 95% CI, 1.15 to 9.28) were associated with a higher odds of developing inpatient complications. No association was present between summer surgeries and SSIs (p=0.486). Conclusions: The results of this study show that overall complication rates following TKA exhibit a seasonal trend, with a peak during the summer months. These results may have some implication in clinical practice and stricter approaches to hospital guidelines during the summer months.

Oxide dispersed strengthened (ODS) steel is an important candidate for Gen-IV reactors. Oxide embedded in Fe can help to trap irradiation defects and enhances the strength of steel. It was observed in this study that the size of oxide has a profound impact on the depinning mechanism. For smaller sizes, the oxide acts as a void; thus, letting the dislocation bypass without any shear. On the other hand, oxides larger than 2 nm generate new dislocation segments around themselves. The depinning is similar to that of Orowan mechanism and the strengthening effect is likely to be greater for larger oxides. It was found that higher shear deformation rates produce more fine-tuned stress-strain curve. Both molecular dynamics (MD) simulations and BKS (Bacon-Knocks-Scattergood) model display similar characteristics whereby establishing an inverse relation between the depinning stress and the obstacle distance. It was found that (110)<sub>oxide</sub> || (111)<sub>Fe</sub> (oriented oxide) also had similar characteristics as that of (100)<sub>oxide</sub> || (111)<sub>Fe</sub> but resulted in an increased depinning stress thereby providing greater resistance to dislocation bypass. Our simulation results concluded that critical depinning stress depends significantly on the size and orientation of the oxide.

This study focuses on measuring the levels of naturally occurring radioactivity in the soil of Swabi, Khyber Pakhtunkhwa, Pakistan, as well as the associated health hazard. Thirty (30) soil samples were collected from various locations and analyzed for 226Ra, 232Th, and 40K radioactivity levels using a High Purity Germanium detector (HPGe) gamma-ray spectrometer with a photo-peak efficiency of approximately 52.3%. The average values obtained for these radionuclides are 35.6 ± 5.7 Bqkg 1, 47 ± 12.5 Bqkg 1, and 877 ± 153 Bqkg 1, respectively. The level of 232Th is slightly higher and 40K is 2.2 times higher than the internationally recommended limit of 30 Bqkg 1 and 400 Bqkg 1, respectively. Various parameters were calculated based on the results obtained, including Radium Equivalent (Raeq), External Hazard (Hex), Absorbed Dose Rate (D), Annual Gonadal Equivalent Dose (AGDE), Annual Effective Dose Rate, and Excess Lifetime Cancer Risk (ELCR), which are 170.3 ± 24 Bqkg 1, 0.46 ± 0.06 Bqkg 1, 81.4 ± 2.04 nGy h 1, 582 ± 78.08 μSvy 1, 99.8 ± 13.5 μSv Gy 1, and 0.349 ± 0.04, respectively. These values are below the limits recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) in 2002. This study highlights the potential radiation threats associated with natural radioactivity levels in the soil of Swabi and provides valuable information for public health and safety

The increasing number of subscribers and demand of multiplicity of services has turned Multi-Server Authentication (MSA) into an integral part of remote authentication paradigm. MSA not only offers an efficient mode to register the users by engaging a trusted third party (Registration Centre), but also a cost-effective architecture for service procurement, onwards. Recently, Lu et al.’s scheme demonstrated that Mishra et al.’s scheme is unguarded to perfect forward secrecy compromise, server masquerading, and forgery attacks, and presented a better scheme. However, we discovered that Lu et al.’s scheme is still susceptible to malicious insider attack and non-compliant to perfect forward secrecy. This study presents a critical review on Lu et al.’s scheme and then proposes a secure multi-server authentication scheme. The security properties of contributed work are validated with automated Proverif tool and proved under formal security analysis.
