COVID-19: Attacks the 1-Beta Chain of Hemoglobin and Captures the Porphyrin to Inhibit Human Heme Metabolism
Authors: wenzhong liu , hualan Li
Published: April 2020

The novel coronavirus pneumonia (COVID-19) is an infectious acute respiratory infection caused by the novel coronavirus. The virus is a positive-strand RNA virus with high homology to bat coronavirus. In this study, conserved domain analysis, homology modeling, and molecular docking were used to compare the biological roles of certain proteins of the novel coronavirus. The results showed the ORF8 and surface glycoprotein could bind to the porphyrin, respectively. At the same time, orf1ab, ORF10, and ORF3a proteins could coordinate attack the heme on the 1-beta chain of hemoglobin to dissociate the iron to form the porphyrin. The attack will cause less and less hemoglobin that can carry oxygen and carbon dioxide. The lung cells have extremely intense poisoning and inflammatory due to the inability to exchange carbon dioxide and oxygen frequently, which eventually results in ground-glass-like lung images. The mechanism also interfered with the normal heme anabolic pathway of the human body, is expected to result in human disease. According to the validation analysis of these finds, chloroquine could prevent orf1ab, ORF3a, and ORF10 to attack the heme to form the porphyrin, and inhibit the binding of ORF8 and surface glycoproteins to porphyrins to a certain extent, effectively relieve the symptoms of respiratory distress. Since the ability of chloroquine to inhibit structural proteins is not particularly obvious, the therapeutic effect on different people may be different. Favipiravir could inhibit the envelope protein and ORF7a protein bind to porphyrin, prevent the virus from entering host cells, and catching free porphyrins. This paper is only for academic discussion, the correctness needs to be confirmed by other laboratories. Due to the side effects and allergic reactions of drugs such as chloroquine, please consult a qualified doctor for treatment details, and do not take the medicine yourself.
A Universal Porous Adsorbent for the Selective Capture of Carbon Dioxide
Authors: Taheri Qazvini Omid , Telfer Shane G.
Published: April 2020

Efficient and sustainable methods for carbon dioxide (CO2) capture are essential. Its atmospheric concentration must be reduced to meet climate change targets, and its removal from sources such as chemical feedstocks is vital. While mature technologies involving chemical reactions that absorb CO2 exist, they have many drawbacks. Porous materials with void spaces that are complementary in size and electrostatic potential to CO2 offer an alternative. In these materials, the molecular CO2 guests are trapped by noncovalent interactions, hence they can be recycled by releasing the CO2 with a low energy penalty. Capacity and selectivity are the twin challenges for such porous adsorbents. Here, we show how a metal-organic framework, termed MUF-16 (MUF = Massey University Framework), is a universal adsorbent for CO2 that sequesters large quantities of CO2 from a broad palette of gas streams with record selectivities over competing gases. The crystallographically-determined position of the CO2 molecules captured in the framework pores illustrate how complementary noncovalent interactions envelop CO2 while repelling other guest molecules. The low affinity of the pore environment for other gases underpins the strikingly high selectivity of MUF-16 for CO2 over methane, nitrogen, hydrogen, acetylene, ethylene, ethane, propylene and propane. Breakthrough gas separations under dynamic conditions benefit from short time lags in the elution of the weakly-adsorbed component to deliver a repertoire of high-purity products. MUF-16 is an inexpensive, robust, recyclable adsorbent that is universally applicable to the removal of CO2 from sources such as natural gas, syngas, flue gas and chemical feedstocks.

Pregnancy-induced hypertension is a high-risk affecting almost all the vessels, particularly those of uterus, kidney, placental bed and brain result in the symptoms called Vascular Symptoms. Thus, it, directly and indirectly, have an effect on the physical and psychological QOL of pregnant women. The aim of this study was to assess the effect of Vascular Symptom Management Package (VSMP) on the Quality of Life (QOL) of pregnant women with PIH. A quantitative approach with the true experimental design was adopted. One hundred twenty women with PIH were selected for study by using a purposive sampling technique. Subjects were randomly assigned to an experimental and control group by using Sequentially Numbered, Opaque Sealed Envelops (SNOSE) (60 in Experimental group & 60 in Control group). The data analyzed by using descriptive and inferential statistics.  Paired 't' test used to compare the pre-test and post-test QOL scores within the group. The inferential statistics results revealed that the post-test QOL score is decreased in the control group and increased in the experimental group significantly. Independent sample ‘t’ test used to compare the pre and post-test QOL scores between experimental and control groups. The mean post-QOL score of the experimental group was higher than that of the mean post QOL score of the control group. This shows a significant increase in the QOL score in the experimental group. Hence it can be interpreted that VSMP is effective in improving the QOL. PIH is a life-threatening condition. The findings of this study show the effectiveness of VSMP improves the QOL. So VSMP is a nurse-led intervention that can be implemented to effectively reduce the vascular symptoms and improve the QOL of pregnant women with PIH.

Contraceptives are the methods, medicines, or devices which are used to prevent pregnancy. The women can select any kind from the available contraceptives. The objectives are to investigate the types of contraceptive methods used by Iraqi women of reproductive age and to throw lights on their complications.  A cross-sectional study had been done in the outpatient department of gynecology and obstetrics of Maternity and Children Hospital in Al-Diwaniya city on 400 women of reproductive age between (16-45) years during the period from 20th of September 2016 to 30th of March 2017. A questionnaire distributed among participating women. All the involved women gave their informed consent after describing the aim of the study and ensuring the confidentiality of the data.  The data were gathered and analyzed statistically. The study revealed that the most commonly used contraceptives were oral pills, the intrauterine device (IUD),  injections, and the condom  (53.7%, 35,7%, 7.5%, 3%), respectively. Oral pills are the most commonly used method in all age groups. The complications were present in (55.0%) of women of reproductive age, and they were present in (69.2 %) of users of the Intra-Uterine Device followed by pills users (45.5%). The most common complications for the oral contraceptives were pain, malaise, and psychiatric disturbances (21.8%, 10.6%, 8.3%), respectively, while in the case of Intra-Uterine Device, the most common complications were bleeding and infection (31.4%, 21.6%) respectively. Injection contraceptive users had suffered from the infection (14.3%). The women’s age, residence, level of education, occupation, and economic status show a significant association with the use of contraceptives methods. The oral contraceptive pills and Intra-Uterine Device are the most frequently used contraceptives. The most common complaints were bleeding, infection, and pain. There is a significant association between the use of contraceptives methods and the women’s age, residence, level of education, occupation, and economic status.

Published: April 2020

Bone-Patellar Tendon-Bone autograft (BPTB) and four-strand semitendinosus-gracilis (hamstring) graft are the most common methods for reconstructing anterior cruciate ligament but there is still controversy over the best method. The aim of this study was to compare the therapeutic results of two methods of BPTB and four-strand semitendinosus-gracilis (hamstring) grafts using arthroscopic treatment in patients with anterior cruciate ligament (ACL) rupture. This retrospective study was performed on 85 patients with ACL rupture aged 17-45 years who referred to Imam Khomeini Hospital in Ahwaz from the beginning of 2016 to the end of 2017 who had undergone two years of ACL reconstruction surgery, either by bone-patellar tendon-bone autograft (BPTB) (open surgery) (n=23) or four-strand hamstring autograft (semitendinosus-gracilis) (by arthroscopy) (n=25). Lysholm score was used for knee functional status assessment, Lachman test for tendon laxity, and pivot shift test for strength evaluation. The 36-Item Short-Form Health Survey questionnaire (SF-36) was also completed and compared at the last follow-up. Patients were also evaluated by type of daily activity (heavy or light activity). There was no significant difference between the two groups in the Lysholm score (P>0.05) and both groups were classified as “Good”. There was no significant difference between the frequency distribution of patients based on Lachman test results and pivot shift results (P>0.05). None of the patients in the two groups had any rupture within two years after treatment. Both groups had good satisfaction with treatment and quality of life and there was no statistically significant difference between the mean SF-36 scores (P>0.05). There was no significant difference between the two groups in the light and heavy activity groups. Although complication in short-term follow-up was more in patients undergoing open surgery, the functional level and treatment satisfaction in patients treated by open surgery (bone-patellar tendon-bone autograft) and arthroscopy (four-strand hamstring autograft) were not significantly different after two years. Therefore, according to the surgeon's diagnosis or the patient's choice, both methods can be selected; method with acceptable therapeutic outcomes in reconstructing the anterior cruciate ligament.

Alzheimer and Dementia were denoted as continuous decline of Brain functions. It particularly affects those who are in the age between 65 and more. The decline of brain functions cause sudden decline of memory Power, thought Process, using language skill and other learning capability. Proper treatment methods are unavailable for Alzheimer, but with certain medication the deterioration may be delayed. The 2011 population censes reads that there are 104  milions of old people and 53 million are female and 51 million are males. Between 1961 and 2011, the elderly population has increased extensively. The reason for this situation were continuously decreasing fertility rate and reduction in the mortality rate and finally due to development of health care system in India. The Population change leads to the change of fertility rate and mortality rate provide bulge in elderly generation as compared to younger ones. In India, this is very common in rural and urban areas. In State level data of elderly population kerala (12.6%), Goa (11.2%) and Tamilnadu (10.4%) takes first, second and third  respectively. The simple reason was the good healthcare system available in the above said states. The Percentage of Alzheimer affected elders are anticipated from 8% to 19% in 2050. Certainly, therefore young India today will turn in to a rapidly ageing India in the coming decades.

The efficiency of selection and breeding work in animal husbandry depends largely on the accuracy of the evaluation of the breeding value of animals. The integration of molecular genetics into applied science made it possible to assess the genetic potential of animal productivity not only on the basis of phenotype data but also directly at the DNA level. The study was conducted on the basis of Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences. The object of the study was DNA samples obtained from the blood of Holstein cows belonging to the stud farm “named after Lenin” of Atninsky district of the Republic of Tatarstan. Animal blood was taken from the tail vein using vacutainer tubes with 100mM EDTA. DNA was isolated from the blood in the amount of 100 µl using a set of reagents for DNA extraction from the “Ampliprime DNA-sorb-B” clinical material (NextBio, Russia), according to the method presented by the producer. DNA fragment amplification was performed in T100 Thermal Cycler (Bio-Rad, USA) and on MyCycler programmable Thermal Cycler (Bio-Rad, USA). After amplification, each DNA fragment obtained by us in the study of TG5, CSN3, LGB genes, was subjected to cleavage by a restriction endonuclease. Hydrolysis was conducted at 37°C for 12 hours. The analysis of polymorphism of candidate genes of dairy productivity of leptin, thyroglobulin, kappa casein and beta-lactoglobulin with the use of PCR-RFLP was carried out. The most common were homozygous TG5CC, CSN3AA and heterozygous LEPCT, LGBAB genotypes. The study of the effect of polymorphism of these genes on milk production showed that animal carriers of LEPCT, TG5TT, CSN3AB, LGBBB genotypes have the best indicators of dairy productivity.

At the present stage of development of market economy, one of the most important tasks of the agricultural sector in Russia is to increase the production of agricultural products, which depends on the sustainable development of livestock industries and their intensification based on modern achievements. The agro-industrial complex and its basic type of economic activity - agriculture - are the leading system-forming spheres of the economy of the Chuvash Republic, which form the agri-food market, food and economic security, labor and settlement potential of rural territories. One of the tasks of the Chuvash Republic State program “Development of agriculture and regulation of the market of agricultural products, raw materials and food of the Chuvash Republic” for 2013-2020 is to stimulate the growth of production of main types of agricultural products and food products. A prerequisite for increasing agricultural production is increasing livestock productivity. The experience of using biological stimulants and feed additives under qualified use, with a predetermined task and in optimal quantities, indicates a rather high economic efficiency and safety for animals and humans.  Research has been conducted to study the effect of para-aminobenzoic acid on the quality of meat in young cattle. The experiments were carried out in the educational experimental farm of the Chuvash State Agricultural Academy. Three groups of young cattle were formed on the principle of 15 animals each. The control group received the main diet, to the first experimental group, para-aminobenzoic acid was added to the main diet at a dose of 0.5 mg per 1 kg of live weight, the second experimental group – 1 mg per 1 kg of live weight.  An organoleptic assessment of the quality of meat and meat broth indicates the biological usefulness of the meat of bull-calves treated with para-aminobenzoic acid. The chemical composition of the meat of bull-calves does not change significantly with the use of this vitamin.

The effectiveness of dairy cattle breeding largely depends on the intensity of use of the breeding stock. At the same time, the factor of the duration of economic use of animals is gaining importance, which affects not only the production economy, but also the improvement of stocks and breeds. The lifelong productivity, the quantitative and qualitative growth of the stock, the amount of capital investment in its formation and the efficiency of operation depend on the term for the productive use of cows. The terms of breeding and production use of animals are direct linked with the biologically possible longevity of each animal, in turn, the duration of the productive period of cattle is in the range of 12-17 lactations. The influence of feed on production is associated primarily with the level of digestion and assimilation. The digestive capacity of the digestive tract of animals can be improved by selecting the optimal ratio in the diet of rough, juicy and concentrated feeds, i.e. optimization of animal feeding types. We conducted an analysis of milk productivity in lactating cows, when using AVMC feed additive in the diet. The experiment was conducted in the conditions of the dairy farm of Biryuli CJSC of the Vysokogorsky District of the Republic of Tatarstan on three groups of lactating cows. For the experiment, 30 cows were selected, 10 in each Holstein black-and-white breed according to the principle of analogues. Studies have shown that AVMC with rapeseed oil seeds and AVMC with fus in the diet of lactating cows provided higher animal productivity and positively affected the chemical composition of milk.

The objective of this study was the analysis of adaptogenic effects of chitosan at gamma-irradiation. The study of radioprotective properties of chitosan was carried out on male mice having the weight of 20-25 g, exposed to gamma-irradiation at the doses of up to 800 bar at the Gamma Panorama unit (radiation source – Cs137, gamma dose rate – 14 R/min, duration of irradiation – 58.5 min). 4 experimental and 2 control groups with 7 animals in each have been formed. The medicine dose schedule, allowing to identify both the prophylactic effect and the therapeutic effect of chitosan, was used in the experiment. It was found out in experiments on white mice, with the purpose of determining 50% lethal dose (LD50) that chitosan belongs to the substances of hazard class 4 because its LD50 considerably exceeds 5000 mg/kg; at this, the toxicity of chitosan decreases parallel to its molecular weight decrease. The prophylactic and therapeutic effect of low-molecular chitosan (molecular weight 5-10 kDa) as abdominal injection at the doses of 200 mg/kg of body weight. It has been demonstrated that the mice from the experimental group I that received chitosan 3 days before the irradiation remained alive throughout the entire observation period (30 days).  In the animals of II, III, IV experimental groups that received chitosan in 3, 9 and 22 days after the irradiation, the survival rate by the experiment end was 86, 43 and 29%, respectively, with the 100% death of animals in the control group I (irradiated animals without the use of chitosan) and full safety of animals in the control group II (non-irradiated animals).

Published: April 2020

Metallothioneins (MTs) are intracellular metal-protein which not alone have inactivated heavy metals but also have traced elements while improving the antioxidant status. Serum levels of some heavy metals and trace elements showed toxic levels in the end-stage renal failure. This study is aimed to determine the serum level of metallothionein in patients with chronic kidney disease (CKD) and to show the effects of hemodialysis on its level. This cross-sectional study included 125 patients with CKD managed with regular hemodialysis. Estimated glomerular filtration rate (eGFR) was calculated by using the Cockroft and Gault equation adjusted to the body surface area (ml/min/m2), and 4 variable modified diet in renal disease (4-v MDRD) equation (ml/min/1.73m2). The mean ± SD of serum metallothionein was significantly less than the corresponding level of healthy subjects (1113.4±289.5 pg/ml versus 1536.0±341.4 pg/ml). Hemodialysis improves the serum level of metallothionein to attain 1437.6±406.1 pg/ml. There is a non-significant correlation between serum metallothionein with the eGFR and hemodialysis did not produce a significant effect on the correlation between serum metallothionein with eGFR.  We conclude that serum metallothionein level is a useful prognostic marker for CKD and hemodialysis plays a role in the recovery of serum metallothionein level.

For the Rotahaler (P-value 0.3), Revoliser (P-value 0.5) a significant improvement was observed with Direct pharmacist intervention when compared with other two interventions. Different critical steps that were more frequently inappropriately performed are shaking before actuation, breathout before inhalation, pressing the canister once, hold breath for at least 5-10 seconds, exhaling away from DPI, fast & deep inhalation for DPI. Direct pharmacist instruction has more impact on study participants compared to other interventions in improvement of before and after counselling mean checklist scores, lesser inhaler technique errors were observed when compared with other interventions provided. Other materials can be used along with direct pharmacist intervention for a better understanding of the patients.
Table Manners
Authors: Wesolowski Christopher
Published: April 2020

Why do we eat the way we do? It is a simple question, but one that is rooted in a deep history of social customs and politics. This paper surveys the past thousand years of table manners through looking at popular courtesy handbooks both translated and written in late medieval Western Europe. It has been argued that table manners are imposed by the royalty and the upper echelons of society in order to have control over the functions of the middle and lower classes, but this paper extends this idea to explore how the population sought to either make fun of or emulate their higher ups. By looking at the history of table manners a great deal can be explored regarding the way in which medieval peoples thought about how they ate, and why it mattered.
Public Perception of the Illustrious Redcoat
Authors: Cooley Ivy
Published: April 2020

The redcoat, particularly the uniform itself, has become a symbol of often contrasting ideas. Jane Austen disliked the collective redcoat while others viewed the British infantryman in a more positive light. The redcoat permeated early 19th century society in terms of fashion, literature, and even plays, though still remains shrouded in mystery as to how civilians perceived this conflicting symbol. This paper will argue that the public perception of the redcoat during the Napoleonic era was paradoxical and depended on historical and personal context, though it largely projected a romanticized view of the British soldier. The redcoat symbolized heroism, chivalry, and power, often impressing the public at military events. However, beneath these gaudy coats were mere mortals who could cloak their sins beneath a convenient symbol of morality, effectively fooling the public with their new and pristine identity.

The Great Fire of London of 1666 has often been categorized into history as a major disaster with severe consequences, but also popularly as a great showing of heroism and social recovery in regard to Londoners and their rebuilding process. This paper will analyze first-hand accounts and scholarly arguments regarding The Great Fire of London, establishing the argument for a dreaded period of economic recovery for the lower class, driven by themes of ignorance, social division and greed by the upper classes. From religious officials, to the city’s mayor and other prominent upper-class Londoners, the great disaster seemed like the opportunity to profit and at the same time keep the less privileged away from London’s thriving society.

Authors: DENİZ Çiğdem Damla , KOZANHAN Betül , TUTAR Mahmut Sami , ÖZLER Sibel
Published: April 2020

Amaç: Üçlü test, gebelikte bebekte olabilecek Nöral tüp defektleri, Down sendromu ve Trizomi 18 gibi doğumsal anomalileri taramakta kullanılan ikinci trimester tarama testidir. İnternet, hastaların tıbbi işlemleri daha iyi anlayabilmek için oldukça sık başvurdukları bir kaynaktır. Bu çalışma ile üçlü test konusunda internet sitelerinin okunabilirlik düzeylerinin saptanması amaçlanmıştır. Yöntem: İnternet arama motoru Google'da ‘üçlü test’ ve ‘üçlü tarama testi’ anahtar kelimeleri kullanılarak yapılan aramada toplam 200 internet sitesine ulaşıldı. On cümleden az bilgi içeren siteler, sohbet, forum siteleri çalışma dışı bırakıldı. Okunabilirlik düzeyleri, Ateşman ve Bezirci-Yılmaz formülleri kullanılarak hesaplandı. Bulgular: Dışlama kriterlerinin uygulanması sonrasında 33 internet sitesi değerlendirme için uygun bulundu. Bunlardan %54.5'i özel klinik, %33.3'ü web sitesi ve %9.09’u özel laboratuvarlara ait sitelerdi. İnternet sitelerinin okunabilirlik düzeyinin Ateşman formülüne göre orta güçlükte (57.6); Bezirci-Yılmaz formülüne göre ise lisans seviyesinde olduğu saptanmıştır (12.27). Metinlerin birçoğu üçlü testin testinin tanımı, uygulama zamanı ve testin yorumlanması konusunda bilgi içermekte idi. Ancak, bu metinlerin genelinde yanlış pozitifliğe neden olan durumlardan yeterince söz edilmediği görüldü. Sonuç: İnternet sitelerinde üçlü test ile ilgili bilgilendirme metinlerinin okunabilirlik düzeyinin düşük olduğu saptanmıştır. Mevcut bilgilendirme metinlerinin okunabilirlik ve içerik yönünden revizyonu için bu konuda etkin biyokimya dernekleri ve sağlık kurumlarının işbirliği içinde olması gerektiği kanaatine varılmıştır.

Authors: ARCA Muhammed , CEYLAN Ali
Published: April 2020

Amaç: İnme geçirmiş olan hastalara bakım verenlerinin akut dönem ve kronik dönem hasta bakımına ilişkin depresyon ve yaşam kalitelerini karşılaştırmak amacıyla yapılmıştır. Yöntem: Kesitsel tipte planlanan bu çalışmaya, Diyarbakır Gazi Yaşargil Eğitim ve Araştırma Hastanesi’nin Nöroloji ve Fizik Tedavi kliniklerinde inme tanısı ile yatan 86 hastaya bakım veren yakınları katılmıştır. Hastaya bakım verenlerin demografik bilgileri için kişisel bilgi formu, psikolojik durumlarını değerlendirmek için Beck Depresyon Ölçeği ve yaşam kalitelerini ölçmek için de WHOQOL-Bref-TR Yaşam Kalitesi Skalası kullanılmıştır. Verilerin istatistiksel analizlerinde SPSS 21.0 paket programı kullanılmış, önemlilik testi olarak Ki-kare ve Student t testleri uygulanmıştır. Bulgular: Hastaya bakım verenlerin %46.5’i erkek (n=40), %53.5’i kadın (n=46), %48.8’i evli, %29.1’i lise mezunu, %53.5’i hastanın çocuğu, %12.8’i hastaların eşleri idi. Hasta bakım verenlerinin yaş ortalaması 33.5±12.6 yıl idi. Kronik dönemde, Beck depresyon ölçeğine göre şiddetli derecede depresyonu olanlarda artış olduğu görülmüş, akut ve kronik grup arasında depresyon açısından anlamlı bir istatiksel fark bulunmuştur (p=0.024). Hasta bakım verenlerin akut dönem ve kronik dönemdeki yaşam kalitesi skorlarından fiziksel sağlık (p=0.063), psikolojik sağlık (p=0.212) ve çevre alanı (p=0.114) skorları anlamlı değilken, sosyal ilişkiler (p=0.001) skorunun istatistiksel olarak anlamlı olduğu görülmüştür. Sonuçlar: Hem akut hem de kronik dönemde bakım verenlerin depresyon sıklığı belirgin şekilde artmış ve yaşam kaliteleri ise düşmüştür. İnme rehabilitasyonunda yalnızca hasta odaklı yaklaşım yerine hasta ve bakım veren bireylere odaklı bir yaklaşım benimsenerek doktor, hemşire, fizyoterapist, psikolog ve sosyal çalışmacıdan oluşan multidisipliner bir rehabilitasyon ekibinin eğitim, danışmanlık ve tedavi hizmeti sunması gerekmektedir.
Importância dos animais silvestres como potenciais carreadores de patógenos alimentares
Authors: Moraes Thamíris Pereira , Timm Cláudio Dias
Published: April 2020

Alguns dos micro-organismos mais comumente associados a doenças transmitidas por alimentos (DTA) são Salmonella, Yersinia enterocolitica, Listeria monocytogenes e Staphylococcus coagulase positiva, sendo responsáveis por diversos surtos em todo o mundo. Os alimentos mais comumente envolvidos nos surtos de DTA são os de origem animal. A maioria dos micro-organismos responsáveis pelas DTA podem ser eliminados pelas fezes de quem ingeriu o alimento contaminado. Também a eliminação dos micro-organismos pelas fezes de portadores constitui uma fonte importante de infecção para seres humanos e outros animais. Animais silvestres têm alto potencial para dispersar micro-organismos no ambiente, uma vez que eles se encontram nos mais diversos habitats, entram em contato com animais domésticos e silvestres, alimentos, fômites e pessoas. Portanto, estes animais podem representar importantes reservatórios de patógenos com potencial de contaminar o ambiente e infectar tanto as pessoas quanto outros animais.

Published: April 2020

Objetivou-se com este trabalho caracterizar a composição química, a preferência e a intenção de compra de doces de ambrosia elaborados com ovos de galinha ou de codorna. Foram realizadas análises bromatológicas (matéria seca, cinza, proteína bruta e extrato etéreo), análises sensoriais com 50 consumidores; análise de preferência (escala variando de 7 - gostei extremamente a 1 - desgostei extremamente) e análise de intenção de compra (variando de 1 - só compraria se fosse forçado a 5 - compraria muito frequentemente) das ambrosias testadas. A partir da avaliação bromatológica foi verificado que a ambrosia elaborada com ovos de codorna apresentou maior teor de gordura (p<0,05) do que a elaborada com ovos de galinha. Na análise sensorial, no conjunto dos atributos avaliados, 68% dos consumidores preferiram ambrosia elaborada com ovos de codorna. De forma semelhante, 54% dos consumidores gostaram extremamente da ambrosia elaborada com ovos de codornas, enquanto que apenas 12% atribuíram este mesmo valor a ambrosia de ovos de galinha. Concluiu-se que ovos de codorna podem ser usados na elaboração de doce ambrosia, apresentando aceitação sensorial e potencial mercadológico. No entanto, ovos de codorna aumentam o teor de gordura da ambrosia em comparação com ovos de galinha.

Published: April 2020

A recuperação e criopreservação dos espermatozoides epidídimários é uma ferramenta promissora no resgate e/ou prevenção da perda de material genético de machos valiosos ou estimados, ou mesmo, de animais em risco de extinção. A conservação destes espermatozoides na espécie felina doméstica ainda apresenta resultados conflitantes, dificultando a aplicação da biotécnica na área comercial, para animais de padrão racial desejado. Contudo, inúmeras pesquisas investigam as peculiaridades fisiológicas dos espermatozoides felinos, com o intuído de desenvolver protocolos e meios de criopreservação promissores. Assim, alguns trabalhos já reportaram sucesso na congelação dos espermatozoides epididimários de gatos, bem como, no emprego destas células em técnicas de reprodução assistida (inseminação artificial e fecundação in vitro). Portanto, o presente artigo tem como finalidade explanar os principais avanços na área da recuperação e conservação dos espermatozoides epididimários para os gatos domésticos e, enfatizar as perspectivas futuras destes trabalhos na conservação do germoplasma felino.
