STUDIES AND RESEARCH REGARDING THE UNITARY ENERGY CONSUMPTION OF A RECIRCULATING AQUACOL SYSTEM

This paper aims to highlight the consumption of electricity and caloric energy consumed by a recirculating aquaculture system for the growth of aquatic life. The energy needed to operate a recirculating aquaculture system for fish farming is divided into two categories, namely the electricity needed to operate various technological equipment, the main equipment in a recirculating aquaculture system that uses electricity being recirculation pumps, mechanical filters (some types), UV sterilization facilities and aeration systems. The second category of energy consumed is the caloric energy required for heating / cooling the water in the system and the hall

Single center experience of over 130 pancreatic resection between 2015 and 2019 – „Saint Mary” surgery and transplant department

Clinica de Chirurgie și Transplant, Spitalul „Sf. Maria”, Clinica de Chirurgie, Institutul Clinic Fundeni, București, România, Al XIII-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” și al III-lea Congres al Societății de Endoscopie, Chirurgie miniminvazivă și Ultrasonografie ”V.M.Guțu” din Republica MoldovaIntroducere: Acest studiu a fost propus pentru a putea aduce noi informații despre centrul nostru de chirurgie hepato-bilio-pancreatică, mai cu seama deoarece în ce privește rezecțiile pancreatice (propuse și efectuate pentru tumori cefalopancreatice, ale ampulei Vater, ale corpului sau cozii de pancreas cât si ale coledocului distal). Evoluția în timp a echipei operatorii a avut un rol important în menținerea rezultatelor apropiate de cele din marile centre de chirurgie hepato-bilio-pancreatică din lume. Material și metode: Scopul acestui studiu este de a prezenta experiența clinicii in rezecțiile pancreatice, dar și să analizeze și să compare rezultatele noastre cu cele din literatură. Inițial, numărul mediu anual de rezecții pancreatice a fost relativ mic, însa în ultimii doi ani, am efectuat cu mai mult de 40% de rezecții pancreatice. Prezentarea această are, de asemenea, rolul de a evidenția importanța unei baze de date naționale ce facilitează urmărirea postoperatorie a pacienților și calcularea ratei de supraviețuire. Rezultate: Am analizat numărul total de rezecții pancreatice (cefalice, centrale, distale) țn perioada 2014-2019, efectuate de mai mulți operatori pentru patologii pancreatice și de calea biliară principală distală, țn cadrul centrului de Chirurgie Generală si Transplant a Spitalului Clinic “Sfânta Maria”, București. Pe baza analizei acestora, am obținut rezultate mult similare cu cele din literatură. Concluzii: Recuperarea postoperatorie a unui pacient ce a suferit o rezectie pancreatică este țn mod cert influențata de comorbiditățile preexistente și de experiența chirurgului. Analizând rezultatele obținute în clinica noastră si comparându-le cu cele din literatură, considerăm ca nivelul nostru de performanța este unul mediu-mare, în special deoarece numărul de rezecții pancreatice anuale a crescut considerabil în ultimii doi ani.Background: This study is meant to bring new pieces of information regarding our hepato-biliary and pancreatic surgical center, especially regarding pancreatic resections (suggested and conducted for cephalopancreatic tumors, ampullary tumors, tumors of the body and tail of the pancreas or distal choledocus tumors). Our team’s evolution and progress has an important role in keeping our results similar to those of the large international hepato-biliary and pancreatic surgical centers. Methods and materials: The aim of this study is to present our clinic’s experience with pancreatic resections, as well as to analyze and compare our results with those described in literature. At the beginning, the mean number of pancreatic resections was small, but in the last two years, we have performed at least 40% more pancreatic resections. The presentation is also meant to emphasize the importance of a national database to facilitate patient follow-up and survival rate calculus). Results: We analyzed a number of patients who underwent pancreatic resections (cephalic, central, distal) performed in our clinic for malignant and benign pathologies of the pancreas, but also biliary pathologies, between 2014 and 2019. After studying the results, the morbidity and mortality rates obtained in our surgical clinic can be compared to those described in literature. Conclusion: The postoperative recovery of a patient that underwent a pancreatic resection is definitely influenced by the preexistent comorbidities and the experience of the main surgeon. By analyzing the results obtained in our clinic and comparing them with those mentioned in literature, we think that our performance level can be considered medium-large, particularly since the number of annual pancreatic resections has grown considerably in the last two years

Central pancreatectomy - indications revisited

Institutul Clinic Fundeni, București, Al XI-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” din Republica Moldova și cea de-a XXXIII-a Reuniune a Chirurgilor din Moldova „Iacomi-Răzeșu” 27-30 septembrie 2011Pancreatectomia alternativă la rezecțiile standard (duodenopancreatectomia cefalica și pancreatectomia distală) pentru leziuni situate la nivelul istmului și corpului de pancreas. Principalul avantaj este reprezentat de conservarea atât a funcției exocrine cât și a celei endocrine a pancreasului. Dezavantajul major este reprezentat de morbiditatea postoperatorie crescută, reprezentată în principal de fistula pancreatică. Cele mai frecvente indicații ale pancreatectomiei centrale sunt reprezentate de tumorile benigne și cu potențial redus de malignizare. Chiar dacă acest procedeu chirurgical este contraindicat în carcinomul ductal de pancreas, totuși, o serie de alte malignități speciale ale pancreasului cum ar fi metastazele pancreatice ale altor neoplazii sau pancreatoblastomul pot beneficia, în anumite situații, de acest tip de intervenție chirurgicală. Deși nu este o procedură chirurgicală foarte frecvent utilizată, pancreatectomia centrală, își găsește locul în arsenalul rezectiilor pancreatice.Central pancreatectomy has emerged as a pancreas-sparing alternative technique to standard pancreatic resections (i.e. pancreatico-duodenectomy and distal pancreatectomy) for pancreatic lesions located to the isthmus and body. The main advantage is related to a better preservation of both exocrine and endocrine pancreatic functions. Conversely, the major concern is related to the high postoperative morbidity, mainly related to the postoperative pancreatic fistula rate. The most frequent reported indications for central pancreatectomy are represented by benign and low-malignant lesions of the pancreas. Although central pancreatectomy is not indicated for ductal adenocarcinoma of the pancreas, however, for certain special malignancies of the pancreas (i.e. metastasis to the pancreas of others neoplasia, pancreatoblastoma), central pancreatectomy has been proven to be a safe operation. Although central pancreatectomy is not a frequent operation, it should be included in pancreatic surgeons’ armamentarium for certain indications

THE INFLUENCE OF HAMMERS` PERIPHERAL SPEED ON THE PERFORMANCE OF THE HAMMER MILLS

Cereal milling is a complex process resulting in a wide variety of particles that differ in size, surface or composition. Ensuring a rational regime regarding the technological process of hammer mills operation, actually refers to the correlation of the indices to ensure the functioning of the mills at optimal values. The peripheral speed of hammers is one of the decisive factors in the milling process. Speed limitation is determined by fodder resistance, the construction of working parts and their durability. In the paper we study the influence of hammers` peripheral speed on the product subjected to milling, through a series of experiments under exploitation conditions

An unusual case of gout in the wrist: the importance of monitoring medication dosage and interaction. A case report

<p>Abstract</p> <p>Background</p> <p>Gouty arthritis of the wrist is uncommon although gout itself is the most common inflammatory arthritis in older patients. Some known risk factors for the development of gout include trauma, alcohol use, obesity, hyperuricaemia, hypertension and diabetes mellitus. As well, certain medications have been shown to promote the development of gout. These include thiazide diuretics, low dose salicylates and cyclosporine. We present a case of gouty wrist pain possibly precipitated by a medication dosage increase as well as medication interactions.</p> <p>Case presentation</p> <p>A 77 year old male presented with right wrist pain. Redness and swelling was present at the dorsal aspect of his wrist and range of motion was full with pain at end range upon examination. One week prior, his anti-hypertensive medication dosage had been increased. The patient's situation continued to worsen. Radiographic examination revealed changes consistent with gouty arthritis.</p> <p>Conclusion</p> <p>It is important for clinicians treating joint conditions to be aware of patients' comorbidities, medication usage and changes in dosages. Education of patients with gout is of prime importance. Clinicians should educate patients that gout may occur at any joint in the body not only the lower limb. Patients should be aware of the signs and symptoms of an acute gouty attack and be made aware that changes in certain medication dosages may precipitate an attack. Awareness of radiographic changes associated with gout is still of importance although these changes are not seen as frequently as they have been in the past due to better control of the disease.</p

CONSIDERATIONS REGARDING THE HARVESTING TECHNOLOGIES OF JERUSALEM ARTICHOKE

Jerusalem artichoke (Helianthus tuberosusL.) is not cultivated on the large surface that cereals, vegetables or potatoes so mechanizes technologies are not very often encountered. In this paper are presented few technologies used on the country where this culture occupied large surface and not only

CONSIDERATIONS ON THE EXTRACTION TECHNOLOGY OF SUGAR SORGHUM JUICE

Lately there has been an increase in drought periods but also an increase in population and therefore in consumption of food and fuel while arable land remains the same which leads to the cultivation of species with high energy potential and high nutritional potential as drought resistant, species of sorghum. The sorghum is used for: food (flours, juices, syrups, vinegar, etc.), for animal feed, but also in the industry for fuel, energy, building materials, paper, proposes to carry out an analysis of the technologies for obtaining juice from sorghum

A Garlic Derivative, S-allylcysteine (SAC), Suppresses Proliferation and Metastasis of Hepatocellular Carcinoma

Background: Hepatocellular carcinoma (HCC) is highly malignant and metastatic. Currently, there is no effective chemotherapy for patients with advanced HCC leading to an urgent need to seek for novel therapeutic options. We aimed to investigate the effect of a garlic derivative, S-allylcysteine (SAC), on the proliferation and metastasis of HCC. Methodology/Principal Findings: A series of in vitro experiments including MTT, colony-forming, wound-healing, invasion, apoptosis and cell cycle assays were performed to examine the anti-proliferative and anti-metastatic effects of SAC on a metastatic HCC cell line MHCC97L. The therapeutic values of SAC single and combined with cisplatin treatments were examined in an in vivo orthotopic xenograft liver tumor model. The result showed that the proliferation rate and colony-forming abilities of MHCC97L cells were suppressed by SAC together with significant suppression of the expressions of proliferation markers, Ki-67 and proliferating cell nuclear antigen (PCNA). Moreover, SAC hindered the migration and invasion of MHCC97L cells corresponding with up-regulation of E-cadherin and down-regulation of VEGF. Furthermore, SAC significantly induced apoptosis and necrosis of MHCC97L cells through suppressing Bcl-xL and Bcl-2 as well as activating caspase-3 and caspase-9. In addition, SAC could significantly induce the S phase arrest of MHCC97L cells together with down-regulation of cdc25c, cdc2 and cyclin B1. In vivo xenograft liver tumor model demonstrated that SAC single or combined with cisplatin treatment inhibited the progression and metastasis of HCC tumor. Conclusions/Significance: Our data demonstrate the anti-proliferative and anti-metastatic effects of SAC on HCC cells and suggest that SAC may be a potential therapeutic agent for the treatment of HCC patients. © 2012 Ng et al.published_or_final_versio
