Synthese und Charakterisierung metallischer Cobalt-Nanopartikel in kolloidalen Systemen

Der Fokus der Arbeit lag auf Darstellungsmoglichkeiten von metallischen Cobalt-Nanopartikeln. Als Synthesemethode wurde die Reduktion von Metall-Salzen mittels Heisinjektion gewahlt. Die Sparte der Precursor-Materialien umfasst Cobalt(II)-Acetat Tetrahydrat, Cobalt(II)-Stearat und Cobalt(II)-Hydroxid. Als Primar-Tenside kamen Olsaure, Stearinsaure und Laurinsaure zum Einsatz. Als Co-Tensid wurde Trioctylphosphin verwendet, das Reduktionsmittel war 1,2-Dodecandiol und das Losungsmittel Dioctylether. Die unterschiedlichen Parameter der Synthesen, wie z.B. Wachstumszeit und –temperatur, sind anhand optimierter Versuchsreihen charakterisiert worden. Alle Systeme wiesen ein mit dem LaMer-Modell vereinbares Verhalten auf. Dabei zeigte sich vor allem die Precursor-Konzentration als ein leistungsfahiger Parameter, um die Keimbildungs- und Wachstumsphasen zu steuern. Zur Morphologie- und Grosenbestimmung der Partikel wurde Transmissionselektronenmikroskopie eingesetzt. Die Kristallstrukturen der Produkte konnte uber Rontgenpulverdiffraktomtetrie aufgeklart werden. Die Wechselwirkung zwischen den metallischen Partikeln und den Primar-Tensiden wurde mittels Fourier-Transform-Infrarotspektroskopie untersucht. Um Einblicke in das magnetische Verhalten der Teilchen zu gewinnen, wurden magnetometrische Messungen am SQUID durchgefuhrt. Der Einsatz der Produkte in magnetische Kompositmaterialien, sowie die Verwendung von dynamischer Lichtstreuung und der Scherrer-Formel zur Grosenbestimmung werden kurz diskutiert.
A Machine Learning Based Approach for the Identification of Insulin Resistance with Non-Invasive Parameters using Homa-IR

Type-2 diabetes mellitus (T2DM) is a significant concern since it is anticipated to reach over 693 million individuals by 2045. Identification and quantification of insulin resistance requires a particular blood test which is complicated, time-consuming and most importantly invasive, making it not feasible for routine day-to-day activities of a human being. With the development of recent machine learning approaches, identification of insulin resistance could be performed without clinical procedures. In this work insulin resistance is identified based on machine learning approaches using non-invasive techniques. Eighteen parameters are used for identification of insulin resistance; such as age, gender, waist size, height, etc. and a combination of these parameters. Experiments are conducted on the CALERIE dataset. Each output of the feature selection method is modelled over different calculations such as logistic regression, CARTs, SVM, LDA, KNN, etc. The proposed approach is verified using Stratified cross-validation test. Results show that using Logistic regression, SVM and few other versions for identification of insulin resistance, accuracy up to 97% has been achieved with standard deviation of 1% compared to 66% with Bernardini et al. [5] & Stawiski et al. [11], 61% Zheng et al. [35] and 83% Farran et al. [32]. Major benefit of the proposed approach is that a person may forecast the insulin resistance and thus future odds of diabetes may be monitored on a daily basis using non-clinical approaches. While the same is not practically possible with clinical procedures.
DILLENIA INDICA LINN.-A MULTIPURPOSE MEDICINAL PLANT OF ASSAM

Dillenia indica is a well-known medicinal plant which thrives in varied agro-climates. It is native to Northeast India, but is widely distributed throughout the Himalayan range. Various studies on the plant reveals the presence of diverse biologically active chemical compounds associated with curing different ailments such as diabetes, inflammations, diarrhea, cancer, ulcer, microbial diseases, hematic disease, hepatic problems, dental problems, cardiovascular problems, hyperlipidmia and others. Most of the biological activities are contributed by the wide varieties of compounds present in fruit and leaves of D.indica. Various scientific investigations have proved that Proanthocyanidins and 3,5,7-Trihydroxy-2-(4'-hydroxybenzyl)-chroman-4-one present in the fruit of D.indica are responsible for minimizing the severity of diabetes and diabetic nephropathy. Betulinic acid isolated from D.indica has anticancer property. In addition to the therapeutic properties, the mucilage of D.indica is used as an important ingredient of various pharmaceutical formulations. Various factors affecting the chemical composition of D.indica such as temperature, annual season rainfall, pH, harvest date, climate, land and cultivation methods are discussed in this review. In view of the medicinal and pharmaceutical importance of the plant, it is quite worthy to review the active constituents and clinical effectiveness of D.indica.
Synthesis, pharmacology, and structural analysis of opioid peptides: Cyclic somatostatin analogs which include unusual amino acids with conformationally restricted side-chain groups

This work relates the activities of Somatostatin-derived opioid peptides to their 3dimensional structures. Due to the flexibility of peptides, they adopt multiple conformations. This flexibility leads to ambiguity in the development of structure-activity profiles. Here flexibility is reduced by incorporation of amino acids with conformationaQy restricted side-chain groups. These groups are restricted to certain topographies by cyclization or biased through substitution at the 3 carbon. The opioid activities of these peptides are determined by brain binding radioligand coiiq)etition assay, in vitro activity in the mouse vas deferens (MVD) and guinea pig ileum (GPI) smooth muscle twitch-height inhibition assays, and in vivo m the mouse warm water tail-flick latency assay. Their 3-dimensional structures were determined through a variety of 2D 'H NMR including TOCSY, ROESY, DQF-COSY, and COSY-35, as well as molecular modeling including energy minimization and molecular dynamics. By knowing the activity of the peptides, and their preferred conformations, a reasonably confident structure-activity profile was generated. Analogs of H-D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2 (CTAP) A^ch mcorporated the conformationaUy restricted amino acids |3-methy^henylalanine (4 isomers), |3-methyhryptophan (4 isomers), and four side-chain group cyclized amino acids as well as unrestricted D-Trp were synthesized. The peptides range in ^ opiate binding afBnity fi'om low nanomolar range to >S|jM, and 5 opiate binding a£5nity fi'om 161 nM to >15 |iM.

Heterosis in the lactation curves of Girolando cows with emphasis on variations of the individual curves

ABSTRACT Linear and nonlinear models were used to evaluate the effect of heterosis on the components of the lactation curves of different crossbred groups of cows from Girolando cattle. Data consisted of 233,587 test-day milk yield records from 33,995 primiparous cows from 1998 and 2014. The Wood’s linear model (WDlin), Wood’s nonlinear model (WDnlin), Wilmink’s model (WL) and Ali and Schaeffer’s model (ASH) were used to estimate individual peak milk yield (PY), day of peak milk yield (PT), 305-day milk yield (TMY), different persistency measures and parameters of lactation curves. The quality of fit of models was different for the genetic groups. The WL model was used to the estimation of heterosis because of the best fit of lactation curve. The heterosis effect was significant (P < .001) for TMY, PY and for the ‘a’ parameter of WL model (initial production). For TMY and PY, crossbred cows presented 14.64% and 20.60% larger yields than the average of the parental breeds, respectively. The heterosis effect from crossbreeding presents more benefits for the components of initial stage of milk yield and milk yield at the peak and with a lesser extent with the two final stages (persistency).
Physicochemical and Sensory Properties of Low-Fat Ice Cream Made with Inulin and Maltodextrin as Fat Replacers. الخواص الفیزیائیة والکیمیائیة والحسیة للمثلجات القشدیة منخفضة الدهن المصنعة من الإنیولین والمالتودکسترین کبدائل للدهن

This study was performed to formulate and evaluate a low-fat, reduced-calories soft serve ice cream using inulin or maltodextrin as a fat replacer. Six batches of ice cream mixes with different fat content (2, 4, and 6%) was prepared by partial replacement of milk fat with either inulin or maltodextrin at levels of 2, 4, and 6% (w/w). A control batch was made with 8% milk fat without adding any fat alternatives. The chemical composition and physicochemical properties of ice cream mixes were determined. A sensory evaluation was also performed on the final products initially and monthly during storage at -18°C for two months. The results indicated that the use of either maltodextrin or inulin as a fat replacer in `low-fat reduced-calorie ice cream formulations can improve the properties of these products. However, the type and level of fat replacer used affects differently on various physical properties such as density and viscosity. It has been also concluded that it was possible to formulate a low-fat, reduced-calorie ice cream with a healthier effect by adding inulin as a healthier fat replacer, alternative to maltodextrin. Good product was obtained with nutritional, technological, and sensory acceptance.

El hundimiento de la evaluación online: una perspectiva de la situación actual

No cabe duda de que el año 2020 será reconocido como uno de los años en los que mayor impulso ha tenido la enseñanza online, todo derivado de la pandemia mundial del SARS-CoV-2. Los centros educativos de todos los niveles cerraron y los profesores tuvieron que ponerse manos a la obra para trabajar con sus alumnos de manera virtual. Muchos de estos profesionales tenían poca o nula experiencia con el uso de herramientas para la enseñanza a distancia. Pero, no cabe duda de que el problema no ha sido únicamente la poca formación del profesorado en relación con la Tecnología Educativa. Esta situación ha puesto en relieve uno de los grandes problemas de la educación: entender la evaluación como un proceso en el que se comprueba el mero logro de un conocimiento teórico. Se juntan, por tanto, dos problemáticas: un mal entendimiento del proceso evaluativo y docentes que no saben cómo actuar en situaciones de enseñanza online.
Isolation and Identification of Fungal Species Associated with Fruits Spoilage in Bwari Market Abuja, Nigeria

Spoilage of fruits imparts great economic loss and a potential health hazard to the general populace. A research was conducted to identify the different types of fungal flora responsible for the spoilage of fruits in Bwari market, Abuja, Nigeria. Seventy fruits that showed decayed symptomatology and thirty healthy ones were procured from Bwari market. Sections of the rotten and healthy fruits were obtained using a sterile blade, inoculated onto Potato Dextrose Agar and incubated at 27°C for five days. All other mycological techniques were carried out using standard methods. The result showed the presence of Aspergillus niger, Rhizopus nigricans, Mucor mucedo, and Fusarium oxysporum. However, Aspergillus niger. (58.06%) was found to be the most dominant spoilage causing organism on fruits vended in Bwari market while Fusarium oxysporum (9.68%) was the least abundant fungal flora. However, the pathogenicity of Rhizopus sp. was found to be higher than that of all the remaining fungal species. This can be attributed to the predisposal and nature of fruits handling and storage in the market. Thus, because all the fungal species identified were known to produce toxins that could impart severe food poisoning, attention of the Original Research Article Mairami et al.; JAMB, 12(4): 1-6, 2018; Article no.JAMB. 42620 2 authorities concerned and the health care providers is needed towards orienting the vendors on the hygienic methods of storing fruits to prolong their shelf-life and the general populace on the dangers associated with the consumption of fruits from Bwari market without thorough washing with saline water more especially those fruits that showed spoilage symptomatology.
The Effect of Different Levels of Zinc on Morpho-Physiological Parameters, Seed Yield Attributing Characters and Seed Quality of Wheat

A Study on Different Types of Stress among Women and its Management

Stress is the body’s response to daily events that occur in one’s life. Everyone experiences stress, but in many different ways. Stress can be positive, helpful and motivate women to achieve notable goals. But stress can also be negative and destructive, taking its toll on many lives. When stress becomes chronic or excessive, it becomes harder to adjust and cope. Chronic stress builds up so that stress seems like a normal way of life for some women. Oftentimes women are so busy that they do not take time to slow down long enough to think about how stress is negatively affecting them. Women in India have come a long way after independence. From just a skilled homemaker, women today have acquired skills and capabilities of not just being a homemaker but being at par with their male counterparts. This is the new generation of women, who wants to pursue their dream career. But this life is not a milk and honey situation.
α-Integrins dictate distinct modes of type IV collagen recruitment to basement membranes

Basement membranes (BMs) are cell-associated extracellular matrices that support tissue integrity, signaling, and barrier properties. Type IV collagen is critical for BM mechanical and signaling functions, yet how it is directed into BMs in vivo is unclear. Through live-cell imaging of endogenous localization, conditional knockdown, and misexpression experiments, we uncovered distinct mechanisms of integrin-mediated collagen recruitment to Caenorhabditis elegans gonadal and pharyngeal BMs. The putative laminin-binding αINA-1/βPAT-3 integrin was selectively activated in the gonad and recruited laminin, which directed moderate collagen incorporation. In contrast, the putative Arg-Gly-Asp (RGD)-binding αPAT-2/βPAT-3 integrin was activated in the pharynx and recruited high levels of collagen independent of laminin. Through an RNAi screen, we further identified the small GTPase RAP-3 (Rap1) as a pharyngeal-specific PAT-2/PAT-3 activator that modulates collagen levels. Together, these studies demonstrate that tissues can use distinct mechanisms to direct collagen incorporation into BMs to precisely control collagen levels and construct diverse BMs.
Influence of Negative Life Events on Depression Among In-School Adolescents In Southwest Nigeria

This study investigated the influence of various negative life events on adolescent depression among in-school adolescents in Southwest Nigeria and whether there is gender difference in the association. The descriptive research of the survey type was adopted for the study. The population of the study was all the adolescents, both male and female, in all secondary schools in the southwest of Nigeria. A total of 1650 adolescents between the ages of 12 and 18 years were selected using multistage sampling technique. A self designed questionnaire titled “Assessment of Negative Life Events and Depression Scale” (ANLEDS) was used to elicit information from respondents. The instrument was validated and the reliability was ensured using test re-test method. The reliability co-efficient was 0.75 at 0.05 level of significance. The data collected were analyzed using descriptive analysis for the general question raised while hypotheses 1 was tested using Pearson Product Moment Correlation and hypotheses 2 was tested using student’s t-test at 0.05 level of significance. The result showed that negative life experiences are significantly related to the development of depressive symptoms among adolescents and the association is influenced by gender difference. Based on the findings, it was recommended that school counsellors should organize programmes to create more awareness and encourage adolescents to discuss their challenges with a view to reducing adolescent depression in Southwest Nigeria.
DIAGNOSTIC POTENTIAL OF SELECTED SALIVARY PROTEOMICS FOR AUTONOMIC NERVOUS SYSTEM ACTIVITY ASSESSMENT

The clinical assessment of autonomic nervous system (ANS) functioning, enabling the diagnosis of autonomic neuropathy present in the course of many diseases, is currently based on performing simple cardiovascular reflexes (Ewing tests), analyzing heart rate variability (HRV) or heart rate turbulence (HRT), examining skin sweating or recording neurophysiological tests (e.g. microneurography). Laboratory assessment of ANS function is very scarce and practically only includes the plasma assessment of noradrenaline as a surrogate for the biochemical indicator of sympathetic activity. Recently, the possibility of evaluation of selected compounds present in saliva as laboratory markers of not only oral diseases but also systemic diseases has been raised. This work focuses on a brief description of the anatomy and physiology of the salivary glands and describes the formation of saliva, its composition and the use of this bodily fluid in laboratory diagnostics. In addition, the paper specifically discusses the possibility of determining selected compounds that are considered to reflect autonomic activity. A review of the literature indicates primarily four proteomics: two neuropeptides (vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) that are co-transmitters in autonomic fibers, chromogranin A, a synaptic vesicle protein and α-amylase, a hydrolytic enzyme pre-digesting carbohydrates in the oral cavity. These are currently the most widely investigated agents for their usefulness as laboratory markers of ANS activity.
Enteric Virus Removal from Water by Coal-Based Sorbents: Development of Low-Cost Water Filters

Using poliovirus type 1 (Sabin) and dechlorinated tap water, several coal-based sorbents were tested for their capacity to remove viruses from water. The sorbents included bituminous coal from Giridih, India, pretreated/impregnated with either alum, ferric hydroxide, lime or manganese dioxide. Filtrasorb-400, commercially available active carbon, was used as a reference. In batch tests, with input virus concentration of 2.34-2.83×106 PFU l−1 and sorbent concentration of 10 g l−1, alum pretreated coal removed about 96% of the virus when pH of the water was between 6.3 and 8.9. Virus sorption was rapid and a plateau was reached in 30 min. Compared with the active carbon, alum pretreated coal exhibited greater sorption energy and about one log higher limiting poliovirus sorption capacity. Downflow column study indicated the potential of alum pretreated coal as a filter media for removing enteric viruses from water. A previous study showed this sorbent to be capable of removing enteric bacteria as well. Water filters prepared from such low-cost material may prove useful for domestic use in rural areas of India and other developing countries.
Impact of climate change on crop adaptation: current challenges and future perspectives

Climate change (i.e. changes in rainfall pattern and temperature) is a global issue affecting all regions and almost all sectors of life. This paper reviews the impact of climate change on crop adaptation and highlighted the recent advances used against these abiotic stresses. Reports have predicted agriculture is most vulnerable sector to climate change. The increasing climate variability has serious threats to crop adaptability and availability. Thus, climate change has threatened the food security. Therefore coping strategies to mitigate the threats to food security are matter of urgency. This can help to mitigate the impact of climate change on crop adaptation. The feasible adaptation practices that could be adapted include sowing time adjustments, stress tolerant varieties and short duration cultivar. The government and policymakers should support sustainable agriculture, farming practices and new technologies. The use of new genetic engineered methods can help to produce more transgenic plants against these environmental extremes.
