Polyhydroxybutyrate (PHB) production by Halomonas boliviensis isolated from waste water
Authors: Singh Anuradha , Srivastava Vivek
Published: July 2022

Plastic materials are often utilized as plastic packaging and have various uses since their longevity and consistency. Plastic products are generally not biodegradable or persist in our surroundings, posing major harm to the ecology. Biopolymers, or bioplastics, are developing as a blessing in the fight against waste buildup. Polyhydroxybutyrate (PHB) is a biopolymer that can be used instead of manufactured polymers. PHB is a fatty storage substance that accumulates inside microbes' cell walls when stressed. Halophilic microbes can be highly useful in manufacturing PHB since they are cheap, and PHB extraction is considerably easy in halo-tolerant species. As a result, our research emphasizes the identification of PHB-generating halotolerant species of microbes using untreated wastewater. Nile blue A and Sudan Black B staining were used to identify PHB favourable strains. The effective microbe generated PHB on a large scale utilizing sewage as the medium.

Linear optimization model for mobile cluster heads to improve the lifetime of sensor network
Authors: Rakesh K. K , Kumar P. Senthil
Published: July 2022

Mobile elements are used in wireless sensor network to increase the longevity of network by minimizing the overloading of one hop sensors. Mobility has proven very useful in reducing the formation of energy holes by balancing the load among all the sensor nodes. The paper proposes exploiting mobile cluster heads to move along a predetermined trajectory to collect data. As autonomous moving strategies impose heavy overhead and data latency issues, predetermined trajectories have proven successful in improvising the lifespan of network. The contributions of the paper are twofold. First we have proposed a predetermined trajectory model along with a cluster formation procedure for the cluster heads to involve in data collection. The cluster heads stop for a fixed time duration “t” at each rendezvous point for data collection. Second, we have proposed a mathematical formulation to optimize the sojourn time duration of thecluster head based on the one hop residual energy of the sensornodes.

Published: July 2022

Two sections were developed for this project: vehicle safety and automation systems. The first part of this project is to use the IoT to monitor highway accidents. The purpose of this project is to provide safety to drivers by requiring them to wear seat belts or helmets. This condition is vehicle-based, ignition will not start until the previous condition is met, and the surveillance section will be notified in the event of an accident on the highway. Accidents that occur on the highway can be monitored using a microcontroller, sensors connected to the main controller, accident detection circuits, and IoT. The project will be able to detect if the driver has consumed alcohol. If he consumes alcohol, the alcohol sensor in our project can detect the alcohol content and turn off the ignition to prevent accidents. Accidents can also be detected from the value of the vibration sensor. Whenever an accident occurs, the vibration sensor sends information to the microcontroller so that it can determine if an accident has occurred. All current status of the vehicle is sent to the Telegram application with the help of the bot.

Authors:   The University of Dodoma, Ndibalema Placidius
Published: July 2022

This paper highlights key barriers to the accessibility of basic education among pastoralist communities in Tanzania. It addresses the existing policy requirements in provision of basic education and the mismatch with actual practices which create a dilemma as far as learning for children in pastoralist communities is concerned. A number of factors have been addressed, which include inappropriate cultural values among parents in pastoralist communities as well as other systemic factors. Pupils’ dropout, conflicts, the long distance to school and inappropriate learning environments have been mentioned as some of the inhibitive factors influencing inequalities in accessing basic education in pastoralist communities in Tanzania. Overall, this paper interrogates the existing paradox between policy statements and the actual strategies for providing basic education among vulnerable minority pastoralist pupils. This article recommends deliberate investment and prioritisation of the learning agenda for minority children in pastoralist communities. Specific emphasis should be placed on the utilisation of technology by establishing mobile digital learning solutions to cater for the learning needs of children in these communities.

Authors: Ariyanti Annisa Inas , Dwiyanti Hidayah , Prasetyo Teguh Jati
Published: July 2022

The prevalence of high blood pressure (hypertension) in Indonesia has increased. One of the best dietary recommendations for people with hypertension is Dietary Approaches to Stop Hypertension (DASH). Various product innovations have been developed to support the implementation of the DASH diet, one of them is a food bar. Potential ingredients that support the diet are banana, oat, and spinach. In addition to containing high fiber and potassium, these three ingredients are also low in sodium, so they are good for heart health. This study aims to determine the formulation of a food bar that has an acceptable sensory characteristic and high fiber content.  The research design was non-factorial experimental study using a randomized block design (RAK). The treatment that was tried was the proportion of raja banana : composite flour (oat : spinach flour = 1 : 3) consisting of 4 formulas: P1 (90%:10%), P2 (85%:15%), P3 (80%:20%), and P4 (75%:25%). The result was analyzed using SPSS software. Proportion of banana with composite flour has a significant effect on the results of hedonic variables (taste, aroma, flavor, overall) and hedonic quality (texture quality, color quality, taste quality, aroma quality, flavor quality). The highest fiber content was found in the product formula P4 (3.8g/100g), while the lowest food fiber content was in the food bar formula P1 (1.57g/100g). The result of Effectiveness Index to determine the best formula was P1. The higher amount of composite flour, the lower sensory value of the food bar. However, the higher amount of composite flour, the higher dietary fiber content in the food bar.

The prime objective of the present study was to develop enteric coated chitosan capsule containing capecitabine for targeting colorectal cancer cells. The study describes a new colonic drug delivery system utilizing capsule shells prepared from chitosan. Coating of drug filled chitosan capsule with pH dependent enteric polymer like HPMC K4M / Cellulose acetate phthalate provides it a special feature of releasing drug at colonic pH. The complex formation between HPMC K4M, cellulose acetate phthalate and chitosan capsule gives extended release of drug over longer period. The disintegration time of the developed enteric coated capsule (Batch F2) was found to be 78±0.86 min and drug release was observed to be 97 % at the end of 9 h in pH 8.5 buffer solution simulating the colon fluid. All the prepared batches exhibited no release of drug in the first 3 h in simulated gastric fluid pH 1.2 and intestinal fluid pH 6.8. Thus, the enteric coated chitosan capsule proved to be efficient to deliver the drug at colon in colorectal cancer disease, which minimizes the side effects, of anticancer drug in stomach and upper intestine.
De Aquí y De Allá: Fluid, Boundless, and ExcessiveGénero
Authors: Sanchez Alexandra
Published: July 2022

This essay explores the reality of genre and gender as fluid, boundless, and excessive, especially in Latinx, hemispheric, and feminist contexts. The author continues the necessary problematizing of simplistic notions of genre and also explores women participating in two expressive forms that are coded as masculine, as evidence of the fluidity of gender. Ultimately, the fluidity, boundlessness, and excessiveness of género in a pan-Latinx context is related to the fluidity of subjectivities due to a transcultural self, a self that welcomes mestizaje, not confined by unyielding boundaries. Género should be a system of classification that highlights the borrowing de aquí y de allá (from here and from there).

This essay is an auto-ethnographic narrative of relational knowledge production. I argue that examining the ways in which we guard the boundaries of the normal has implications for how we might theorize Latinx folklore studies, specifically with regard to questions of sexuality, gender, and race. I discuss several critiques articulated by Black, Indigenous, and Latin American LGBTQ+ activists and scholars about the idea of the “queer,” the “quír,” and the “cuir.”
Voice Onset Time of Initial Stops in Najdi Arabic
Authors: Aljutaily Mohammad, F., , Alharbi Bader, Y.,
Published: July 2022

The voice onset time (VOT), which indicates the durational interval from the stop release to the start of the voicing of the following vowel, has long been a prominent research topic in the field of acoustic phonetics. It has shown to be a reliable universal acoustic parameter in discriminating the stop consonants in numerous languages, like English, German, Korean, and various Arabic varieties. It also has been claimed that other factors, such as place of articulation, gender, and vocalic contexts, may affect the productions of the VOTs of the stop categories. Therefore, the present study aims to examine the VOT values of the Najdi Arabic (NA) stops, particularly the plain stop consonants /b, d, g, t, k/, and the potential effects of the place of articulation, gender, and vocalic contexts on their production. Sixty male and female native NA speakers were recruited in this study. The findings revealed that NA has two types of VOTs: positive VOTs with the voiceless stops and negative VOTs with the voiced stops. They also showed that the VOTs of the NA stops become longer when the articulators move back to the oral cavity and shorter in the front cavity. Lastly, the findings reported that the VOTs with short vowels are significantly shorter than the VOTs with long vowels and that gender does not affect the VOTs of the voiced stops, but does affect the VOTs of their voiceless counterparts. Hopefully, the conclusions reached in this study contribute to a better understanding of this interesting acoustic parameter and to the less acoustic literature on Arabic and its various varieties.

Published: July 2022

Introduction:

The extent to which physical therapy (PT) is used after meniscectomy is unknown. The objective of this study was to estimate the extent to which PT is implemented after meniscectomy and to identify factors associated with its utilization.

Methods:

The Mariner PearlDiver database was queried to identify patients who underwent uncomplicated meniscectomy. The number of PT visits for each patient was tabulated. Logistic regressions were used to compare demographic factors associated with no use of PT and use of nine or more PT visits.

Results:

In total, 92,291 patients met inclusion criteria. Of these patients, 72.21% did not use PT and 27.8% used 1 or more PT visits. Of the patients who used PT, 19.76% had 1 to 8 PT visits and 8.03% had 9 or more PT visits. Older age and noncommercial insurance types were associated with no PT use. Male sex, Medicaid, and Medicare were associated with markedly lower odds of increased PT utilization.

Conclusion:

PT is used in the minority of the time after meniscectomy. Among patients who do use PT, however, notable variation exists in the amount of PT visits used. Patient age, sex, insurance status, and geographic variables were independently associated with PT utilization.

What is the role of evidence in shaping suicide prevention policy in Wales?
Authors: Moore Rosie
Published: July 2022

This guidance highlights the importance of utilising evidence in the generation of national suicide prevention policy. However, suicide is a uniquely challenging context for evidence gathering, as population level data is often delayed and inexact. Moreover, the true reason why each individual life is lost to suicide is – by its very definition – unobtainable. Therefore, a broad range of evidence, guidance, expertise, and research must be drawn upon to answer the unanswerable.

TÓM TẮTĐặc điểm hình ảnh trên CLVT của u nguyên bào thần kinh sau phúc mạc (UNBTK SPM) ở trẻ em. Đánh giá giá trị CLVT trong chẩn đoán UNBTK SPM ở trẻ em.Mục tiêu: nêu lên các đặc điểm hình ảnh của UNBTK SPM ở trẻ em trên CLVT. Đánh giá độ nhạy, độ đặc hiệu, giá trị dương tính, giá trị âm tính, độ chính xác của CLVT trong chẩn đoán xác định UNBTK SPM và đánh giá sự lan tràn của bệnh.Đối tượng và phương pháp: 111 bệnh nhân với 112 khối u SPM được chụp CLVT bằng máy CLVT GE 2 dãy đầu dò tại khoa Chẩn đoán hình ảnh (CĐHA) Bệnh viện Nhi Trung ương từ năm 2006 đến 2008, trong đó có 50 UNBTK (chẩn đoán theo tiêu chuẩn*) và 62 u SPM khác (chẩn đoán bằng GPB). Chúng tôi phân tích các đặc điểm trên CLVT (số lượng, vị trí, kích thước, tỉ trọng trước và sau tiêm thuốc cản quang…), từ đó chẩn đoán xác định hoặc loại trừ UNBTK, sau đó đối chiếu với kết quả phẫu thuật và GPB hoặc tiêu chuẩn chẩn đoán UNBTK từ đó tính toán các giá trị độ nhạy, độ đặc hiệu, giá trị dự báo dương tính, âm tính, độ chính xác của CLVT.Kết quả: qua phân tích chúng tôi rút ra 7 đặc điểm của UNBTK SPM trên CLVT là khối bờ thùy múi, giới hạn không rõ, không có vỏ, ngấm thuốc không đều, mức độ ít và trung bình hay có vôi hóa, bao quanh các mạch máu lớn. Trong đó 3 dấu hiệu bờ thùy múi, giới hạn không rõ và bao quanh mạch máu là có giá trị chẩn đoán nhất. Các dấu hiệu còn lại không đặc hiệu và ít có giá trị chẩn đoán xác định nếu xét trên từng dấu hiệu riêng lẻ (các giá trị chẩn đoán như độ nhạy, độ đặc hiệu….dao động từ 52% đến 96%). Tuy nhiên, khi kết hợp nhiều dấu hiệu (≥ 4/7dấu hiệu) thì giá trị chẩn đoán tăng đáng kể (82%-98%). Đối với đánh giá sự lan tràn của bệnh, CLVT có thể đánh giá xâm lấn tại chỗ và di căn khá chính xác: thận (>94%), mạch máu (100%), các tạng trong ổ bụng (>75%), hạch SPM (>85%).Kết luận: trên CLVT hình ảnh của UNBTK là khối bờ thùy múi, không có vỏ, ngấm thuốc không đều, mức độ ítvà trung bình hay có vôi hóa, bao quanh các mạch máu lớn. Trong đó 3 dấu hiệu bờ thùy múi, giới hạn không rõ vàbao quanh mạch máu là các dấu hiệu có giá trị chẩn đoán nhất. Chúng ta nên sử dụng nhiều dấu hiệu trên CLVT kếthợp để tăng giá trị chẩn đoán UNBTK. CLVT khá chính xác trong đánh giá sự lan tràn của bệnh.

TÓM TẮTUng thư biểu mô tế bào gan (HCC) là một trong những nguyên nhân hàng đầu gây tử vong, xếp thứ 5 ở nam giới và xếp thứ 8 ở nữ giới trong số các ung thư nguyên phát. Tỉ lệ mắc HCC cao nhất được thấy ở châu Phi khu vực cận Sahara, Đông Á, Đông Nam Á. Tính chung trên toàn thế giới, tại các nước đang phát triển, tỉ lệ mắc trong 100.000 dân đối với nam giới là 17,43, đối với nữ giới là 6,77. Tại các nước phát triển, tỉ lệ này tương ứng là 8,71 và 2,86 [2],[6]. Việc điều trị HCC hiện nay vẫn còn là thách thức đối với y học đương đại. Đối với HCC giai đoạn sớm, phẫu thuật cắt gan, ghép gan và đốt sóng cao tần là các phương pháp điều trị triệt để, có tỉ lệ sống 5 năm đạt 50-70% [18]. Nhưng trong thực tiễn, tỉ lệ HCC được phát hiện chủ yếu ở giai đoạn tiến triển, không thể phẫu thuật (nonresectable). Đối với HCC giai đoạn tiến triển, không thể phẫu thuật, thì nút động mạch gan qua catheter (TACE) kết hợp với truyền hóa chất tại chỗ qua catheter là là phương pháp điều trị hỗ trợ hiệu quả nhất hiện nay, giúp kéo dài thời gian sống cho người bệnh [19],[20]. Hiệu quả nút mạch sẽ giảm đi rõ rệt nếu không gây tắc được tất cả các nguồn cấp máu cho khối u [13],[19]. Trong thực tế lâm sàng, nhiều khối ung thư gan còn được cấp máu từ các hệ ĐM khác ngoài hệ ĐM gan. Việc nhận biết được các nguồn cấp máu cho khối u từ ngoài hệ động mạch gan là rất cần thiết để đảm bảo cho hiệu quả nút mạch cũng như tránh được những biến chứng có thể xảy ra do các vòng bàng hệ.

TÓM TẮTĐặt vấn đề: biến chứng chảy máu não thứ cấp trong vùng nhồi máu là nguyên nhân hàng đầu gây nên diễn biến lâm sàng nặng nề sớm ở bệnh nhân thiếu máu cục bộ não. Dự báo sớm biến chứng này có ý nghĩa quan trọng trong việc lựa chọn phương pháp điều trị phù hợp, dự phòng biến chứng cũng như có kế hoạch can thiệp sớm nếu biến chứng xảy ra. Các yếu tố dự báo hiện tại chưa đáp ứng được đầy đủ yêu cầu về độ chính xác, tính thực tiễn cũng như an toàn bức xạ cho việc ứng dụng rộng rãi trên lâm sàng. Nghiên cứu này được tiến hành nhằm đánh giá vai trò sự phá vỡ hàng rào máu não trong dự đoán biến chứng chảy máu trong vùng tổn thương.Phương pháp: chỉ số thấm hàng rào máu não được tính trên hình ảnh chụp cắt lớp vi tính tưới máu não ứng dụng phương trình Gjedde-Patlak. Giá trị dự báo của chỉ số này được đánh giá thông qua mối tương quan của nó với biến chứng chảy máu.Kết quả: nghiên cứu này cho thấy chỉ số thấm hàng rào máu não cao hơn ở các tổn thương có biến chứng chảy máu. Đồng thời, có mối tương quan chặt chẽ có ý nghĩa thống kê giữa tăng chỉ số thấm hàng rào máu não với nguy cơ xảy ra biến chứng chảy máu não thứ cấp trong vùng nhồi máu. Nghiên cứu cũng đưa ra ngưỡng dự đoán chảy máu thứ phát của chỉ số thấm hàng rào máu não đo tại vùng nhồi máu là 2.7ml/100g/phút. Tại ngưỡng này giá trị dự báo của chỉ số thấm đạt cao nhất.Kết luận: tăng thấm hàng rào máu là một trong những yếu tố nguy cơ của chảy máu thứ phát sau thiếu máu cục bộ não cấp tính. Chỉ số này đo được trên chụp cắt lớp vi tính tưới máu não cũng là yếu tố dự báo của biến chứng này. Phân tích về chỉ số thấm hàng rào máu não cần được tiến hành đồng thời với phấn tích các thông số về tướimáu trên phim chụp cắt lớp đánh giá tưới máu não trên bệnh nhân thiếu máu cục bộ não cấp tính nhằm nâng cao khả năng dự báo biến chứng và có kế hoạch dự phòng và xử trí biến chứng kịp thời.

TÓM TẮTMục tiêu: khảo sát các đặc điểm của kĩ thuật tạo hình xung lực bức xạ âm ARFI trong chẩn đoán phân biệt hạt giáp lành - ác.Đối tượng và phương pháp nghiên cứu: nghiên cứu mô tả cắt ngang. 130 hạt giáp được thực hiện siêu âm quy ước B-mode và tạo hình xung lực bức xạ âm ARFI bằng máy siêu âm Acuson Siemens S2000 tại Medic từ tháng 08/2011 đến tháng 10/2012. Tất cả hạt giáp đều được thực hiện FNAC sau đó để làm giá trị đối chiếu. Xử lýsố liệu: phần mềm Medcalc.Kết quả: khảo sát 130 hạt giáp gồm 103 hạt lành tính, 23 carcinôm tuyến giáp dạng nhú và 4 tổn thương dạng nang. Giá trị VTQ trung bình của mô giáp lành, hạt giáp lành và ác tính lần lượt là 1,41m/s (range 0,84 – 3m/s); 2,15m/s (range 0,8 – 4,04m/s) và 3,2m/s (range 0,9 – 9,22m/s). Tại điểm cắt 2,16m/s, độ nhạy và độ chuyên củaARFI trong phân biệt hạt giáp lành tính và ác tính là 79,4% và 53,7% (diện tích dưới đường cong ROC là 0,731). Độ chênh lệch giá trị VTQ giữa mô giáp bình thường và hạt giáp (lành, ác) có độ nhạy là 79,5% và độ chuyên là 51% tại điểm cắt 0,63 (diện tích dưới đường cong ROC là 0,72). Có sự phụ thuộc có ý nghĩa thống kê giữa VTI và phânbiệt hạt giáp lành - ác, ngưỡng sai lầm a = 0,001.Kết luận: VTQ của hạt giáp và độ chênh lệch giá trị VTQ giữa mô giáp bình thường và hạt giáp có thể giúp ích trong chẩn đoán phân biệt hạt giáp lành tính và ác tính. Có thể phối hợp với VTI để tăng thêm giá trị chẩn đoán.
