Bouea macrophylla Griff is a member of the Anacardiaceae family, which has edible fruits. Due to the high nutritional value, appealing taste, and attractive color, the fruit juice of B. macrophylla has the potential to be developed as a functional beverage. The present study was conducted to determine the phytochemical profile of B. macrophylla fruit juice using GC-MS and LC-MS/MS. GC-MS analysis was performed with the Agilent Technologies 7890 Gas Chromatograph with automated sampling and tandem Agilent 5975 Mass Selective Detector and peak analysis with the Chemistation data system. LC-MS/MS QTOF analysis was performed with UPLC Waters I Class and tandem MS/MS Xevo G2S QTOF with UNIFI software. GC-MS analysis identified five compounds with a quality match of 90% and above, namely 3-pentadecylphenol (31.68%), 5,5’-(oxybis(methylene)]-bis-2-furancarboxy-aldehyde (5.67%), 5-(hydroxymethyl)-2-furancarboxy-aldehyde (23.51%),  4H-pyran-4-one, 2,3-dihydro-3,5-dihydro-6-methyl (5.00%), and n-hexadecanoic acid (4.71%). Five major compounds were identified for the first time in B. macrophylla fruit juice by LC-MS/MS analysis, i.e., (E)-hexadecyl-ferulate, digupigan A, eburicoic acid, hydroginkgolinic acid, and terminalic acid. The health benefit of some of these detected phytochemicals supports the use of juice as the main ingredient for functional food.

Butuan Bay is an amalgamation of resources and wastes, with the Agusan River as its main river source. Multiple industrial operations near the area make it susceptible to pollution, thereby affecting the aquatic organisms and the people who depend on the bay for food and livelihood. Thus, the main objective of the study was to determine the Mercury (Hg), Lead (Pb), and Nickel (Ni) concentration in the flesh of Marsh clam (Polymesoda expansa) in different mangroves wetlands across Butuan Bay. Heavy metal concentration was assessed using cold vapor atomic absorption spectroscopy for Hg and Atomic Absorption Spectrophotometry for Pb and Ni. The results revealed that Hg and Pb concentrations were below the detection limits (BDL), while Ni concentrations were within the tolerable limits established for bivalves. Human health risk via the consumption of P. expansa was calculated using the estimated daily intake (EDI) and Target Quotient Hazard (THQ). Results show that the EDI of Ni exceeded the oral reference dose, but its THQ was below the standard THQ value. In conclusion, the consumption of P. expansa does not pose any adverse health effects on human health. Still, further investigation and monitoring of the mangrove ecosystems are encouraged to secure the environment's health and the communities that depend on it.
布团湾是资源与废弃物的融合,以阿古山河为主要河源。该地区附近的多重工业活动使其容易受到污染,从而影响了水生生物和依赖该海湾的食物和生计的人们。因此,本研究的主要目的是测定北团湾不同红树林湿地泥鳅肉中汞(Hg)、铅(Pb)和镍(Ni)浓度。采用冷蒸汽原子吸收光谱法测定Hg和原子吸收分光光度法测定Pb和Ni的重金属浓度。结果表明,汞和铅的浓度低于检测限(BDL),而镍的浓度在双壳类动物的允许范围内。利用估计日摄入量(EDI)和目标商危害(THQ)计算了食用白豆的人体健康风险。结果表明,Ni的EDI超过了口服参考剂量,但THQ低于标准THQ值。综上所述,食用白杨不会对人体健康造成不良影响。尽管如此,仍鼓励对红树林生态系统进行进一步调查和监测,以确保环境的健康和依赖环境的社区的健康。

Lasers have been used in a variety of industries, but we will concentrate on their use in medicine, specifically dermatology. I concentrated on three types of lasers in this article (ablation, non-ablative lasers, and fractional lasers). The non-ablative laser causes skin contraction as a result of wound stimulation of collagen during the healing phase in the dermis, upper dermis, and thermal ablation. Laser ablation is more dangerous because it heats up the dermis. A fractional laser affects the inner dermis layer, which contains collagen, rather than the epidermis, which stimulates this vital component. An ablative fractional laser, on the other hand, peels off the skin's outer layer. According to research, these three lasers produce unfavorable outcomes. Therefore, PBM technology was used without thermal interactions and effects on the skin, increasing patient satisfaction with rejuvenation. This is what we concluded through the search engines Scopus, Google Scholar, and the EndNote application.
激光已被用于各种行业,但我们将集中在其在医学上的应用,特别是皮肤科。在这篇文章中,我集中讨论了三种类型的激光器(烧蚀、非烧蚀激光器和分数激光器)。非烧蚀性激光引起皮肤收缩,这是真皮、真皮上部愈合阶段胶原蛋白伤口刺激和热消融的结果。激光消融更危险,因为它会加热真皮层。分数激光影响的是含有胶原蛋白的内真皮层,而不是刺激胶原蛋白的表皮。另一方面,烧蚀式分数激光会剥去皮肤的外层。根据研究,这三种激光产生不利的结果。因此,PBM技术的使用没有热相互作用和对皮肤的影响,提高了患者对年轻化的满意度。这是我们通过搜索引擎Scopus、Google Scholar和EndNote应用得出的结论。

Urine specimens were collected aseptically and inoculated directly onto CLED and MacConkey agar medium and incubated overnight. Single target colonies were sub cultured, and identification was based on culture, morphology, and biochemical characteristics. Enterococci isolates were subjected to biofilm assay (Tube method), and resistance pattern was determined for both biofilm-formers and non-biofilm-formers. Genomic DNA was extracted using the Bioneer kit, and the gene for virulence was detected by PCR and agarose gel electrophoresis. 148 Patients having one or more urinary symptoms were the study population. The aim of the study was to determine the multidrug resistant ability of biofilm-forming Enterococci. A number of growths were encountered; Enterococci accounted for only 9.46% (14), the highest prevalence was seen in the age group 21-30 (35.71%), and females (64.29%) were more prone to enterococcal infection than their males (35.71) counterpart. There is a relationship between biofilm production and antibiotic resistance because multidrug resistant Enterococci isolate produced bands against esp gene with an average of 510kbp. Biofilm forming strains showed the highest resistance to gentamicin and penicillin (83.3%), and vancomycin can be considered a good alternative therapy in enterococcal UTIs because of its lower resistance (75%).
无菌收集尿液标本,直接接种于ccled和MacConkey琼脂培养基上,孵育过夜。单目标菌落继代培养,并根据培养、形态和生化特征进行鉴定。对分离的肠球菌进行生物膜测定(试管法),并对形成生物膜的肠球菌和非形成生物膜的肠球菌进行耐药性分析。采用Bioneer试剂盒提取基因组DNA,采用PCR和琼脂糖凝胶电泳检测毒力基因。148例有一种或多种泌尿系统症状的患者为研究人群。该研究的目的是确定生物膜形成肠球菌的多重耐药能力。遇到了一些增长;肠球菌感染率仅为9.46%(14%),其中21 ~ 30岁患病率最高(35.71%),女性(64.29%)高于男性(35.71%)。由于多药耐药肠球菌分离物产生的esp基因条带平均为510kbp,因此生物膜的生成与抗生素耐药性之间存在一定的关系。生物膜形成菌株对庆大霉素和青霉素的耐药性最高(83.3%),万古霉素的耐药性较低(75%),可被认为是肠球菌性uti的良好替代疗法。

Cracking catalytic palm oil (CPO) into hydrocarbon fuel by saponification pretreatment has been carried out with bentonite and limestone-based catalysts. The catalysts used were Na-bentonite and Limestone NTT which were first analyzed using XRF, XRD, and SEM. Saponification pretreatment was carried out on CPO to facilitate the cracking process using a catalyst. The saponification product in the form of a mixture of soap and glycerol was then analyzed by DSC to determine the degradation temperature. Catalytic cracking is carried out in two stages, namely, the first stage hydrocracking at a temperature of 250-350°C using a stainless steel reactor is the source of catalyst Fe / Cr. The resulting distillate was then cracked again using a Na-bentonite catalyst and a TKNTT catalyst. The resulting fuel is a hydrocarbon fuel which is confirmed from the FT-IR results which indicate the presence of long-chain hydrocarbon compounds. This data is also supported by the results of the GC-MS analysis which shows that the fuel fraction produced is mostly biogasoline. Where cracking using a Na-bentonite catalyst produces a biogasoline fraction of 61.36% and a biodiesel fraction of 38.63%, THAT produces a biogasoline fraction of 88.88% and a biodiesel fraction of 11.11%. The characteristics of the hydrocarbon fuels that have been analyzed show that the calorific value of combustion is 6101 cal/g which is determined using a bomb calorimeter, and the cetane index is 62 which is analyzed using CCI. Both types of hydrocarbon fuels have met the physical requirements that must be possessed by biogasoline fuel based on SNI standards.
采用膨润土和石灰石基催化剂对催化棕榈油进行皂化预处理,将其裂解为碳氢燃料。采用钠基膨润土和石灰石NTT作为催化剂,采用XRF、XRD和SEM对催化剂进行了分析。对CPO进行皂化预处理,以促进催化剂催化裂化过程。然后用DSC分析肥皂和甘油混合物形式的皂化产物,以确定降解温度。催化裂化分两个阶段进行,第一阶段采用不锈钢反应器,在250 ~ 350℃的温度下加氢裂化,为Fe / Cr催化剂的来源,所得馏出物再采用na -膨润土催化剂和TKNTT催化剂裂化。得到的燃料是一种碳氢化合物燃料,从FT-IR结果证实,表明存在长链碳氢化合物。这一数据也得到了GC-MS分析结果的支持,GC-MS分析结果表明,生产的燃料馏分主要是生物汽油。其中,使用na -膨润土催化剂裂解,生物汽油馏分为61.36%,生物柴油馏分为38.63%,生物汽油馏分为88.88%,生物柴油馏分为11.11%。经分析的烃类燃料的特性表明,燃烧热值为6101 cal/g(用弹式量热计测定),十六烷指数为62(用CCI测定)。根据SNI标准,这两种碳氢化合物燃料都满足生物汽油燃料必须具备的物理要求。

Schiff base derived from the reaction of 2-amino phenol and 2-hydroxy-1-naphthaldehyde and its Co (II), and Mn (II) complexes have been synthesized and characterized by solubility test, melting point/ decomposition temperatures, molar conductance, IR and magnetic susceptibility. The number of ligands coordinated to the metal ion was determined using Job’s method of continuous variation. Their molar conductance values indicate that all the complexes are non-electrolytes. Magnetic moment values of the complexes showed that both Mn (II) and Co (II) are paramagnetic. The spectroscopic data of metal complexes indicated that the metal ions are complexed with azomethine nitrogen and deprotonated oxygen atom. Corrosion inhibition of the schiff base and Mn (II) and Co (II) complexes were evaluated using the weight loss method in a 0.1MHCl solution for copper metal. The inhibition efficiency increased with increasing inhibitors concentration. The negative values of Gibb’s free energy of adsorption (ΔGads) confirmed the spontaneity and physical adsorption of the inhibition process which is inconsistent with Langmuir adsorption isotherm.
本文合成了由2-氨基苯酚和2-羟基-1-萘醛及其Co (II)和Mn (II)配合物合成的希夫碱,并用溶解度、熔点/分解温度、摩尔电导、红外光谱和磁化率对其进行了表征。用Job的连续变分法确定了金属离子配位体的数目。它们的摩尔电导值表明所有配合物都是非电解质。配合物的磁矩值表明,Mn (II)和Co (II)均具有顺磁性。金属配合物的光谱数据表明,金属离子与亚甲基氮和去质子化氧原子络合。用失重法评价了希夫碱和Mn (II)、Co (II)配合物在0.1MHCl铜金属溶液中的缓蚀作用。抑制效果随抑制剂浓度的增加而增加。吸附的Gibb自由能为负值(ΔGads)证实了抑制过程的自发性和物理吸附性,这与Langmuir吸附等温线不一致。

Results of phytochemical screening showed the presence of Alkaloid, Flavonoid, Tannins, Glycosides, Anthraquinone, Saponins and Steroid. There is no significance difference between Addawa’ul humma and the standard drug Ciproflxacin (P<0.05). However, the physicochemical analysis result of Addawa’ul humma shows that it has the highest concentration of phosphate and sulphate (0.72 mg/kg and 0.2 mg/kg respectively). Results of the FT-IR indicated that the preparation consists of unsaturated with Alkanol functional group plus additional carbonyl group as shown by the FT-IR Spectra.
该研究评估了Addawa 'ul humma治疗伤寒的疗效。Addawau 'l humma是一种草药制剂,由(芒果、印度楝树、橙子、柠檬和番石榴提取物)组成。并与标准药物环丙沙星作对照试验。植物化学筛选结果显示,黄酮类、单宁类、苷类、蒽醌类、皂苷类和甾体类化合物均存在。阿达瓦乌尔与标准药环丙沙星比较,差异无统计学意义(P<0.05)。然而,对Addawa 'ul humma的理化分析结果显示,它的磷酸盐和硫酸盐浓度最高(分别为0.72 mg/kg和0.2 mg/kg)。红外光谱结果表明,该产物由不饱和烷烃官能团加羰基组成。
