Authors: Ademolu K.O. , Idowu A. B. , Jayeola O. A. 
Published: February 2021

The impact of growth phases on the haemolympy biochemical value of African giant land snail Archachatina marginata was studied. The growth phases were: snailet, juvenile and Adult based on the number of whorls on the shell and weight of the snails. Highest concentration of glucose and lipids were recorded at the juvenile phase (40.20mg/dl), while least values for glucose (20.00mg/dl) and lipids (37.80mg/dl)were recorded during snailer and adult phases respectively. A progressive increase in the concentration of protein was observed as the snails moved from snailetphase to adult phase, hence snails in adult phase had highest concentration of protein in their haemolymph. Growth phases significantly (p<0.05) affected the haemolymph mineral composition of the snails, juvenile phase had the highest values in ca2+,PO4+ and Na+, while the adult phase recorded the least concentration in ca2+, Na amd cl-2. Juvenile growth phase of A. marginata thus has better haemolymph biochemical values than both snailet and adult growth phases.

A study was conducted to determine the effect of supplementing rice straw with pigeon pea forage on rumen and blood metabolites of Yankasa sheep. Sixteen yearling Yankasa ewes were used for the study. A completely randomized design was used with four animals per treatment. A basal rice straw diet was provided ad libitum and pigeon pea forage supplemented at 0.5, 1.0 and 1.5%of the body weight. Rumen and blood samples were collected at 3, 6, 9, 12 and 24 hours post-feeding. Results of the study showed low (1.16-3.81mg/100ml) NH3-N concentration in the unsupplemented ewes. Supplementation at 1 % body weight improved the level of NH3-N concentration to 10.38mg/100ml. Volatile faty acids also increased from 26.33 to 43.33mg/l in 0.0% and 1.0% of body weight pigeon pea forage supplementation. pH variations within treatments remain within acceptable range for rumen microbial activity: There was a uniformly low level of plasma urea nitrogen in the unsupplemented diet across sampling time, supplementing at 1.0% of the body weight had the highest plasma urea nitrogen level with 3 and 6 hours post-feeding being significantly (P<0.05) higher than other sampling time. Levels of packed cell volume and haemoglobin improved from 21.00% and 48% in the supplemented diet to 32.00% and 73% at 1.0% pigeon pea forage supplementation respectively

Published: February 2021

An experiment was carried out to determine the effect of feeding growing snails with two different leguminous plants, Calopogonium muculoides, Pueraria phaseoloides, using pawpaw (Carica papaya) leaf as control. A total of 72 growing snails (Archachatina marginata) of mean weight 74.73/3.5g were used for the feeding trial. The snails were randomly alloted into 3 different groups and each group was replicated 4 times with 6 snails per replicate in a completely randomized design. Snails in T1 were fed pawpaw leaf (control), while snails in T2 were fed Calopogolium muculoides. Parameters measured were feed intake, weight gain, shell length and width and feed conversion ratio. The feeding trial lasted for 12 weeks. The results on growth performances reveal that the highest feed intake was recorded in snails fed pawpaw leaf (PL) which was similar to the those fed Pueraria phaseoloids (PP), while the lowest feed intake was recorded in snail fed with Calopognium muculoids (CM). The highest weight gain was also recorded in snails fed with pawpaw leaf and Peuraria phaseoloids (PP) than those fed Calopognium muculoides (CM). In conclusion, Pueraria phaseoloids could be used as substitute for pawpaw leaf.

Published: February 2021

The impact of management systems on the African giant land snail, Archachatina marginata found in Abeokuta, Nigeria was investigated. The gut microbial load, haemolymph biochemical values (proteins, lipids, glucose, Na+, Ca2+,K+, Cl- PO42+) and proximate composition (crude protein, fat, fibre, ash and carbohydrates) of the flesh were determined in these snails. There were significantly (P<0.05) higher colony forming units (cfu) in the gut of snails from the wild (5.24 x103) than the domesticated snails (3.13 x103). The aemolymph biochemical values and flesh proximate composition were significantly higher in the snails from the wild than the domesticated ones. However, antinutrients and mineral composition of the flesh were not significantly affected by the management systems. The implication of these results on snail meat value in Nigeria is discussed.

Forty five weaner rabbits, aged four weeks of mixed sexes were used to investigate the performance of rabbits fed Gmelina arborea leaf meal (GALM) at 0,10,20,30 and 40% inclusion level. Increasing the level of GALM had no significant effect (P>0.05) on feed intake, weight gain and feed to gain ratio. There was also no treatment effect on nitrogen intake (P>0.05). Furthermore, increasing the dietary level of GALM in the diet also had no significant effect (P>0.05) on faecal nitrogen, nitrogen retained and nitrogen digestibility. However, the cost of feed declined with the corresponding increase in the GALM dietary level. The result shows that Gmelina arborea leaf meal could be fed to grower rabbits up to 40% inclusion level without any adverse effect.

Published: February 2021

Federal University of Agriculture reservoir is one of the recently constructed in Abeokuta, Ogun state, Nigeria, therefore the need to assess the water quality, fish diversity and catch assessment of this new water body. Data on fish species were collected on a forthnight basis using multi-stage gillnet sampling techniques for four months (September- December, 2011). Three sampling stations were randomly selected from the entire reservoir. A variety of sampling methods were used at each site in order to reach every fish species. At the river channel and the floodplain sites, traps, cast nets (2.55cm mesh), seine nets (2.55 x 2 cm mesh), monofilament nylon gillnets (15.55 cm mesh), and hook and line were employed. Efforts were made in order to catch fish species in large abundance. Some sampled fish (dead) were collected and placed in cool boxes and examined within 18 hours of capture. Others were preserved in 15% formalin and stored for later examination. A total of 863 fish specimens were caught during the study period. These were identified and classified into 5 species belonging to 3 families. The percentage species composition of the harvest by numbers and weight for all fish species that contributed more than 1% in all the stations combined, were computed. Study of the physico-chemical parameter such as dissolved oxygen ranged from 5.03 to 7.19mg/l; 26 to 280C temperature; 64.8 to 148ppm alkaline; pH 6.67-6.90; 32.5 to 53.5m transparent; 8.86 to 13.72mg/l nitrate; 0.58 to 0.64mg/l phosphate; 0.024 to 0.069 o/oo saline; 103-270cm deep. pH and water temperature serve as variables since the fluctuation of one affects the values of others. The water quality parameters were favourable for fish production. The gillnet fisheries indicated that different mesh sizes of experimental gillnets were sensitive to different fish species. 67.2mm, 78.4mm and 112mm, mesh sizes were efficient in catching Clarias gariepinus, Barbus occidentalis and the Cichlids respectively. The study has shown that middle water was the most suitable habitat for fish in the reservoir. Water level and temperature were observed to guarantee high fish yield in the reservoir.

Published: February 2021

A 35-day feeding trial involving three hundred (300) five (5) week old broilers was carried out in a completely randomized design to evaluate the haematology, serum biochemical and gastro-intestinal characteristics of broiler finishers fed diets containing a mixture of fermented bovine blood and rumen digesta (FBBRD) meal at dietary levels of 0, 5, 10, 15 and 20 %, respectively. The birds were randomly grouped into five, with sixty birds each and four replicates of fifteen birds per treatment. At the end of the experiment, blood samples were collected from eight birds randomly selected from each treatment for haematological and biochemical analyses. The group on 10 % FBBRD diet had significantly (P<0.05) higher packed cell volume, haemoglobin concentration and red blood cells. Eosinophil values of birds on all the treatment groups except those on 5 % FBBRD dietary level were within the normal range. Serum biochemical analysis of the experimental birds recorded significant (P<0.05) differences in total protein, albumin, creatinine, cholesterol, except blood sugar concentrations. Serum concentrations of sodium and potassium of the experimental birds were also significantly (P<0.05) different. This study suggested that FBBRD meal when properly processed and at 10 % dietary level of inclusion, can be used in broiler finisher production without adverse effects on the physiological indices of birds

Published: February 2021

A 56 day trial was carried out to evaluate the response of West African Dwarf (WAD) bucks fed processed poultry dropping. Nine (9) West African Dwarf (WAD) bucks were assigned to three treatment groups in a completely randomized design (CRD) experiment with 3 bucks per treatment. The diets contained poultry dropping at 0% (T1), 10% sun dried poultry dropping (SDPD, T2) and 10% toasted poultry dropping (TPD, T3). The parameters evaluated included: dry matter intake (DMI), changes in body weight, feed conversion ratio (FCR), heart girth (HGC), body length (BLC) and height at withers, hematological and biochemical indices, and carcass characteristics of the bucks. Proximate analyses of the sun-dried poultry dropping, toasted poultry dropping, the treatment diets and the forages (Panicum maximum and Centrocema spp.) were also carried out. Concentrate dry matter intakes were 184.65g, 150.05g and 183.62g while forage dry matter intakes were 494.04g, 569.70g and 555.66g for T1, T2, and T3 respectively. Concentrate dry matter intake was similar (P>0.05) in T1 and T3 groups, but significantly (P<0.05) higher than the T2 group. The T2 group consumed significantly higher (P<0.05) forage than the T1 and T3 groups. HGC and HWC were 5.67cm, 2.33cm and 4.67cm, and 5.00cm 4.67cm and 4.00cm respectively. T1 and T3 had higher HGC than T2 group, while the T2 group recorded higher HWC than the T1 and T3 groups. The hemoglobin (Hb) values varied significantly (p<0.05) among the treatment means, and they were, 12.30, 11.30 and 12.00g/dl respectively. PCV (%) and WBC(x103/mm3 varied significantly (p<0.05) and the values were 37.00, 34.00 and 36.00 (%), and 39.00, 56.07 and 42.50(x103/mm3 respectively. Neutrophil and lymphocyte were also influenced significantly, the values were, 15.00, 10, and 31.00%, and 83.00, 86.00, and 66.00% respectively. Only serum urea was affected among the biochemical components, and the values were 0.87, 0.90 and 0.97 mg/dl respectively. Dressing percentage were 34.62%, 37.75% and 42.60% for T1, T2 and T3 respectively; the T2 and T3 groups were similar (P>0.05) but T3 was higher than T1. The values for shoulder were 10.67%, 10, 74% and 8.05%; the full gut values were 47.20% 38.56% and 28.68% for T1, T2 and T3 respectively. Liver, kidney and heart were 2.90%, 2.22% and 1.93%; 0.55, 0.47% and 0.42%, and 0.72%, 0.57% and 0.58% for T1, T2 and T3 respectively. T1 showed significantly (P<0.05) higher relative weight values for liver and heart than the T3 group. Inclusion of processed poultry dropping up to 10% in the diets of WAD bucks did not affect their performance negatively. However simple sun drying is recommended based on the results of this study and it is also a cheaper and straight forward processing method for poultry dropping.
Har du draget? – En undersøkelse av ingeniørstudenters kunnskaper og ferdigheter i mekanikk etter eksamen
Authors: Thorvaldsen Per Eilif , Sjursen Therese , Buanes Trygve 
Published: February 2021

I artikkelen presenteres en ny måte å måle kvaliteten i studenters læringsutbytte og undervisningen, ved at det foretas en ny vurdering av kunnskap og ferdigheter i fysikk en god stund etter avlagt eksamen i emnet. Denne vurderingen tyder på at studentene mangler konseptuell forståelse av mekanikk og har lite læringsutbytte i fysikk. Undersøkelsen gjenspeiler at studentene tror de innehar god/tilstrekkelig kunnskap. Det er spesielt interessant, og vi fremsetter hypotesen at dette skyldes undervisningsmetode. Denne måten å evaluere kunnskap på, ved å foreta en test en gitt tid etter avlagt eksamen kan være et godt redskap for å måle en faktisk oppnådd forståelse av fysikk. Videre vil resultatene kunne hjelpe oss til å vri læringsutbyttemålene i retning av konseptuell forståelse istedenfor det nåværende søkelys på det å kunne anvende fysikkens lover. Den foreslåtte metoden kan ha stor overføringsverdi til andre

Published: February 2021

Digitalisering av undervisningssektoren har fått mykje oppmerksemd dei siste månadane etter at samfunnet blei stengt. På grunn av smittevernreglar som avgrensar mogelegheita til fysisk undervisning, må utdanningsinstitusjonane tilpasse undervisninga til romkapasiteten, talet på studentar og ressursbruk til lærarane. Det medfører utfordringar for både studentar, lærarar og administrasjonen.
Dette konferansebidraget skal presentere resultat (erfaringar og refleksjonar) sett gjennom fire perspektiv: pedagogisk, sosial, økonomisk og økologisk. Kva slags digital undervisningsform trivst studentane best med? Kva gir størst læringsutbytte? Korleis blir det sosiale framheva gjennom undervisninga? Er studentane motiverte ved å sjå på ein skjerm? Kor mykje kostar utstyr som trengst til å førebu og gjennomføre digital undervisning? Kva er kostnaden på miljøet for å legge til rette for digital undervisning?
Studien presenterer ei samling av desse fire perspektiv og drøfter om å drive digitale undervisningsformer. Både med tanke på den økonomiske kostnaden til institusjonane og kvar student, med den pedagogiske, sosiale og økologiske kostanden. Det er ein samla vurdering av pengar, tid, ny kunnskap og energi som kan gi eit fullstendig bilete av kor mykje det eigentleg kostar med digital undervisning. Kan vi forbetre undervisningskvalitet med avgrensande resursar?
Anatomic Analysis of a Percutaneous Fixation Technique for the Posterior Malleolus Using Posterior-to-Anterior–Directed Cannulated Screws: A Cadaveric Study and Technique Description
Authors: Kimball Jeff S. , Ruckle David E. , Rajfer Rebecca A. , Johnson Joey P. 
Published: February 2021

Background:
Posterior malleolus fractures are traditionally managed with open reduction and internal fixation or percutaneous anterior-to-posterior screws. We present a third option using a percutaneous technique for the placement of posterior-to-anterior–directed screws. An anatomic safety analysis is done using cadaveric specimens.

Methods:
Using 15 embalmed specimens (10 F and 5 M), a guidewire was placed using the described technique. The posterolateral ankle was dissected to evaluate for damage to vulnerable structures including the sural nerve, peroneal artery, and flexor hallucis longus/flexor digitorum longus/peroneal/Achilles tendons. The distance from the sural nerve and peroneal artery was measured to the guidewire at its nearest point. The tendons were evaluated for traumatic piercings.

Results:
The sural nerve had a mean distance to wire of 5.3 mm (range 0 to 12) and the peroneal artery had a mean distance to wire of 5.7 mm (range 2 to 13 mm) with no traumatic piercings of either structure. The flexor hallucis longus/flexor digitorum longus/peroneal/Achilles tendons had no traumatic piercings.

Conclusion:
This percutaneous technique provides a safe alternative to the standard open and traditional percutaneous techniques. It has limited application and is suitable for noncomminuted minimally displaced posterior malleolus fractures and those with fragile tissues where the morbidity of the soft tissue exposure outweighs the benefit of an open reduction.

Published: February 2021

Amaç: Glioblastoma Multiforme (GBM) erişkinlerde en sık görülen primer malign beyin tümörüdür. Optimal tedavisi, mümkün olan en geniş cerrahi rezeksiyon (maksimum güvenli rezeksiyon) sonrasında adjuvan eşzamanlı kemoradyoterapi ve ardından adjuvan kemoterapidir. Fakat, geriatrik grup optimal tedavi edilmemektedir. Son çalışmalarda genç hastalarla benzer olarak yaşlı grupta da optimal tedavinin fayda sağladığı gösterilmiştir. Biz de, 65 yaş ve üstü GBM’li hastalarda optimal tedavinin sağkalım üzerine etkisini araştırmayı amaçladık.
Yöntemler: Pamukkale Üniversitesi Tıp Fakültesi Tıbbi Onkoloji Polikliniğinde 2010-2018 yılları arasında takip edilen GBM patolojik tanılı 71 hastanın dosyaları retrospektif olarak değerlendirildi. Hastaların demografik ve klinikopatolojik özellikleri dosyadan kaydedildi
Bulgular: Değerlendirilen 71 hastanın 25’i (%35,2) 65 yaş ve üstü, 46’sı (%64,8) 65 yaş altındaydı. Yirmi beş hastanın 11’i (%44) erkek, 14’ü (%56) kadındı. Tüm hasta grubunda ortanca takip süresi 16,2 ay (12,4-19,9), ortanca genel sağkalım süresi 12,5 ay (10,4-14,7 ay) idi.

Published: February 2021

Amaç: İnternal karotis arter gibi supraaortik büyük arter tıkanıklarında mortalite ve kalıcı özürlülük oranı daha yüksektir. Dolayısıyla karotis arter darlıklarının erken tespiti klinik açıdan önem arzetmektedir. Aterom plağının distale olan akımı kısıtlayacak derecede stenoza neden olması sonucunda karşımıza çıkan “sınır zonu infarktı” ise karotis arter darlıklarında normalden çok daha sık olarak karşımıza çıkarak karotis arter darlığı açısından uyarıcı olabilmektedir. Bu çalışmada, kraniyal görüntülemelerinde sınır zonu infarktı izlenen ve etiyolojisinde karotis arter darlığı saptanarak karotis arter stentleme yapılan olgular incelenmiştir.
Yöntemler: Ocak 2017-Temmuz 2019 tarihleri arasında serebrovasküler hastalık tanısı ile takip edilmiş ve karotis arter stentleme yapılmış 120 olgu retrospektif olarak incelenmiş sınır zonu infarktı saptanan 31 olgu çalışmaya dahil edilmiştir.
Bulgular: 31 olgunun yaş ortalaması 68,1±9,6 olup 27 si erkek ve 4 ü kadındı. Bu olguların 8 (%25,8) tanesinde sağ, 7 (%22,6) tanesinde sol, 16 (%51,6) tanesinde bilateral karotis arter darlığı mevcuttu. En yüksek oranda eşlik eden komorbiditeler hipertansiyon 28 (%90,3), hiperlipidemi 22 (%71) ve koroner arter hastalığı 18(%58,1) idi. Olguların17 (%54,8)’inde geçici iskemik atak, 24 (%77,4)’ünde sigara içme öyküsü mevcuttu. 31 olgu radyolojik olarak değerlendirildiğinde 17 (%54,8) tanesinde internal+eksternal, (%16,1) tanesinde izole internal ve 9 (%29) tanesinde izole eksternal sınır zonu infarktı saptandı. Olgulara iskemik inmeden ortalama 22,3±12,2 gün sonra stentleme yapıldığı saptandı. Karotis arter stentleme sonrası 3 olguda minör inme saptandı. Minör inme sebebi ile bu olguların hastane yatış sürelerinin ortalama 6 gün uzadığı izlendi. Olguların pre-op ortalama modifiye rankin skorları 1.35±0.87 iken işlemden 30 gün sonra 1.13±0.99 idi. Tüm olguların birinci ay sonunda yapılan karotis arter doppler ultrasonografi incelemelerinde stent açıklığının tam olarak izlendiği ve restenoz saptanmadığı tespit edildi.
Sonuç: Sınır zonu infarktları karotis arter darlıkları açısından uyarıcı bir iskemik inme paternidir. Klinisyenlerin hastalığın tanınması ve tedavisinin yürütülmesi süreçlerinde etkin bir şekilde mücadele edebilmeleri için farkındalıkları arttırılmalıdır. Bu çalışma, sınır zonu infarktı ile gelen karotis arter darlıklı hasta gruplarında endovasküler stentleme yönteminin güvenli olduğuna ve erken dönemli sonuçlarının fonksiyonel sonlanımlar açısından olumlu sonuçlandığına işaret etmektedir.

Published: February 2021

Amaç: Ağır akut solunum sendromu korona virus 2 (SARS-CoV-2) hastalığı (COVID-19) halen büyük bir sorun olarak tüm dünyada etkisini göstermektedir. Halen SARS-CoV-2'ye karşı antikor tepkileri tam olarak anlaşılamamıştır ve serolojik testlerin klinik yararları belirsizdir. Bu çalışmada COVID-19 geçiren hastaların farklı zamanda alınmış numunelerde Roche SARS-CoV-2 antikor testi ile antikor düzeyleri değerlendirildi.
Yöntemler: Hastanemize 21 kişinin Mart 2020 – Nisan 2020 tarihleri arasındaki SARS-CoV-2 PCR testi bakılmış ve serum numunesi toplanmış kişilerden, Temmuz 2020 ayında tekrar numune alınmış ve toplam 42 numunede Roche SARS-CoV-2 antikor düzeyleri bakılmıştır.
Bulgular: Toplam 21 kişinin ilk numunesinin 7’sinde Anti SARS CoV 2 antikorları negatif, 14’ünde Anti SARS CoV 2 antikorları pozitif olarak bulunmuştur. Negatif olan numunelerin hepsinde RT-PCR sonuçları pozitif olarak saptanmıştır. İkinci numunelerin 1’inde Anti SARS CoV 2 antikorları negatif, 20’isnde Anti SARS CoV 2 antikorları pozitif olarak bulunmuştur. Tüm kişilerin ikinci numuneleri ele alındığında, SARS-CoV-2 antikor değerlerinde hiçbir numunede düşüş saptanmamıştır.
Sonuç: Çalışmada ikinci numunelerde dahi antikor düzeyi negatif ve kısmen düşük cut off değerlerdeki numuneler bulunmaktadır. Bu çalışma gerek antikor düzeylerinin varlığı ve takibi gerekse plazmaferezlerde donör antikor düzeyinin saptanması açısından önem taşımaktadır.
Validation of the Method for Determination of Melamine and Investigation its Trace in Milk from Vietnam by LC-MS/MS
Authors: Hieu-Tran Quang 
Published: February 2021

This work describes a rapid, selective, and sensitive method by using liquid chromatography-tandem mass spectrometry (LC-MS/MS) to detect melamine (MEL) in milk and dairy products. The optimal conditions of liquid chromatographic separation extraction and mass spectroscopy of MEL have also been examined. The linear range for analyte detected by the method was 0.5÷100.0 ng/mL, with correlation coefficients was 0.999. Mean recoveries of the method in the real samples at three spike levels (low, medium, and high) were within the range of 98.5% ÷102.5% (n =7). LOD, LOQ values of the method were 10 and 30 ng/mL, respectively. The influence of the matrix effect on the accuracy, repeatability, and recovery of the process was insignificant. The proposed method was used to quantify the content of this compound in various real samples, which were collected in Ho Chi Minh City-Vietnam in 2020.
