Development and validation of a video-based intervention on self-care practices for patients with hypertension in Malaysian primary care settings.

Introduction: Self-care practices among patients with hypertension have been shown to improve blood pressure control. Video-based interventions (VBIs) are helpful in enhancing patients' selfcare practices. However, validated VBIs in the Malay language for patients in primary care settings are scarce. This study aimed to develop and validate a VBI series in the Malay language to educate patients with hypertension on self-care practices in primary care settings. Methods: This study was conducted in three phases: (1) pre-production, (2) production and (3) post-production. The pre-production phase involved designing the storyboard and scripts, which underwent content validation by content experts and subsequently by patients with hypertension. Once the storyboards and scripts achieved acceptable consensus, the videos were recorded (production phase). The post-production phase included video editing and face validation among patients with hypertension. Statistical analysis included the calculation of the item-level content validation index (I-CVI) and item-level face validation index (I-FVI) during content and face validation, respectively. Results: The storyboards and scripts for five videos were developed. The I-CVI of all videos was 1.0 after two rounds of content validation among six content experts. The I-CVI of all videos was 1.0 among five patients with hypertension. Five videos were recorded and edited, achieving an I-FVI of 1.0 during face validation among 10 patients. Conclusion: A VBI series consisting of five videos was developed and validated for use among patients with hypertension in primary care settings to improve their knowledge of self-care practices.

Complete Genome Sequences of Actinobacteriophages Anaysia and Caviar.

Anaysia and Caviar are temperate siphoviruses isolated from soil using Gordonia terrae 3612 and Mycobacterium smegmatis mc2155, respectively. Anaysia's 52,861-bp genome carries 102 genes, while Caviar's 47,074-bp genome carries 79 genes. Based on gene content similarity, Anaysia and Caviar are assigned to phage clusters A15 and A3, respectively.

Emerging cold plasma treatment on rice grains: A mini review.

Future demand of rice is projected to increase with the increase of global population. However, the presence of bacteria, insects, and fungi has resulted in various changes in the physical and chemical characteristics of rice grain. To make it worse, the overuse of post-harvest chemicals (fungicide and pesticide) has caused possible risks to human health through either occupational or non-occupational exposure. For the last few years, cold plasma has been developed as an alternative non-thermal emerging technology for rice grains treatment due to its ability to inactivate or decontaminate pathogens without causing thermal damage and free of any harmful residues. Therefore, this review describes the operational mechanism of cold plasma treatment technology on rice grains, existing reactor system designs, and parameters influenced by the treatment technology (reactor design parameters and treatment process parameters). Possible advanced investigation on future reactor design modification as well as standard operating range of influenced parameters were suggested for improved efficiency and effectiveness of cold plasma treatment.

Signal Enhancement Evaluation of Laser-Induced Breakdown Spectroscopy of Extracted Animal Fats Using Principal Component Analysis Approach.

In this work, principal component analysis (PCA) was utilized to analyze laser-induced breakdown spectroscopy (LIBS) signals of the extracted chicken fat, lamb fat, beef fat, and lard froze using two different freezing methods. The frozen samples were ablated using a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser with a wavelength of 1064 nm, 170 mJ pulse energy, and 6 ns pulse duration to produce plasma on target surfaces. The samples were ablated using 30-60 shots of the laser beam at different spots. Stronger LIBS signals from the extracted chicken fat and lamb fat were obtained with liquid nitrogen (LN2) method. However, LIBS signals obtained from the freezer freezing method were found to be stronger for extracted beef fat and lard. The PCA was then used to visualize the LIBS spectra of extracted animal fats into a score plot. Data points of each extracted animal fat were divided into three groups representing LIBS spectra collected at the early, middle, and end part of the ablation process. The score plot revealed that the data points of the three groups of frozen extracted animal fats using the LN2 method were more closely clustered than those frozen in the freezer. Good discrimination with 97% of the variance was achieved between the extracted chicken fat, lamb fat, beef fat, and lard using the LN2 method in the three-dimensional score plot. LIBS signals of the extracted animal fats produced from the LN2 method were found to be more stable than those from the freezer method.
