BACKGROUND: Primary spontaneous pneumothorax (PSP) is a common disease in thoracic surgery, and a prolonged postoperative air leakage is the most frequent and troublesome early complication after video-assisted thoracoscopic (VATS) bullectomy. This study aimed to explore the efficacy of polyglycolic acid (PGA) sleeve in preventing postoperative air leakage after a VATS bullectomy for PSP. METHODS: This study was a prospectively randomised clinical study. The patients who underwent a VATS bullectomy were continuously enrolled from January 2015 to June 2016 in the Beijing Chaoyang Hospital and were randomly assigned to the experimental and control groups...

Background: Lumbar hernias are rare. Usually manifest with reducible volume increase in the post-lateral region of the abdomen and may occur in two specific anatomic defects: the triangles of Grynfelt (upper) and Petit (lower). Despite controversies with better repair, laparoscopic approach, following the same principle of the treatment of inguinal hernias, seems to present significant advantages compared to conventional/open surgeries. However, some technical and anatomical details of the region, non usual to general surgeons, are fundamental for proper repair...

Sleeve gastrectomy operations have become popular among restrictive obesity surgeons, due to its effectiveness for losing weight and acceptable complication rates. However, leakage is a significant problem in these operations. In this ex vivo study, we tried to understand mechanisms of leakage and to examine the effects of two different types of frequently referred reinforcement techniques using sutures. The resected gastric specimens that were removed during sleeve gastrectomy operations were used in this ex vivo study...

A large number of pathologies require the resection of the bowel and anastomoses to rejoin the two remaining stumps to regain lumen patency. Various materials have been used to rejoin one bowel end to the other such as catgut, stainless steel, and absorbable sutures. The present method for anastomosis surgery uses an entero-entero anastomosis (EEA) circular stapler with only a staple line. This method can have some drawbacks, such as intracellular fluid leakage and local inflammations. The aim of this study is to design and develop a novel bioartificial polymer with a ring shape made of polyvinyl alcohol (PVA) and gelatin (80/20 ratio (w/w)) loaded both directly with acetylsalicylic acid and with nanoparticles incorporating the same drug to reduce local inflammation even for a prolonged period of time...

Biofortification aims to improve the micronutrient concentration of staple food crops through the best practices of breeding and modern biotechnology. However, increased zinc and iron concentrations in food crops may not always translate into proportional increases in absorbed zinc (Zn) and iron (Fe). Therefore, assessing iron and zinc bioavailability in biofortified crops is imperative to evaluate the efficacy of breeding programs. This review aimed to investigate the advantages and limitations of in vitro and in vivo methods of iron and zinc bioavailability evaluation in the assessment of biofortification program effectiveness...

FODMAP, "Fermentable Oligo-, Di- and Mono-saccharides And Polyols", is a heterogeneous group of highly fermentable but poorly absorbed short-chain carbohydrates and polyols. Dietary FODMAPs might exacerbate intestinal symptoms by increasing small intestinal water volume, colonic gas production, and intestinal motility. In recent years the low-FODMAP diet for treatment of irritable bowel syndrome (IBS) has gained increasing popularity. In the present review we aim to summarize the physiological, clinical, and nutritional issues, suggesting caution in the prolonged use of this dietary treatment on the basis of the existing literature...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery performed worldwide. Improvements in LSG have been suggested to achieve better weight loss or to lessen the complications rates. We propose a change in the standard technique to privilege the use of thinner instruments, the needlescopic sleeve gastrectomy (NSG). METHODS: A 40-year-old female, BMI 40, with no previous abdominal surgery was selected for a NSG. She was placed in a semi-sitting position with the surgeon standing between the legs...

A 75-year-old man underwent thoracoscopic left upper lobectomy for primary lung cancer. Additional ligature plication to the left superior pulmonary vein with absorbable monofilament suture was performed after stapling with an endostapler. Postoperative bronchoscopy revealed penetration of the monofilament thread edge eviscerating across the wall of the left main bronchus. The edge was spontaneously absorbed with no adverse events. Penetration of a thick monofilament thread edge into mediastinal organs should be considered when the thread is located in the mediastinum...

Due to its high adaptability, cassava (Manihot esculenta Crantz) is one of the world's most cultivated and consumed plants after maize and rice. However, there are relatively few scientific studies on this important crop. The objective of this review was therefore to summarize and discuss the available information on cassava cropping in order to promote sustainable practices in terms of production and consumption. Cassava cultivation has been expanding recently at the global scale and is widely consumed in most regions of South America, Africa, and Asia...

BACKGROUND: Surgical wounds (incisions) heal by primary intention when the wound edges are brought together and secured, often with sutures, staples, or clips. Wound dressings applied after wound closure may provide physical support, protection and absorb exudate. There are many different types of wound dressings available and wounds can also be left uncovered (exposed). Surgical site infection (SSI) is a common complication of wounds and this may be associated with using (or not using) dressings, or different types of dressing...

P-arsanilic acid (AsA) is a emerging but less concerned contaminant used in animal feeding operations, for it can be degraded to more toxic metabolites after being excreted by animals. Rice is the staple food in many parts of the world, and also more efficient in accumulating arsenic (As) compared to other cereals. However, the uptake and transformation of AsA by rice is unclear. This study aimed to evaluate the potential risk of using AsA as a feed additive and using the AsA contaminated animal manure as a fertilizer...

Aflatoxins are highly toxic fungal metabolites produced by some members of the Aspergillus species. They are low molecular weight lipophilic compounds that are easily absorbed from the gastrointestinal tract. They contaminate most staple foods, including maize, peanuts, peanut butter and sorghum mainly in the tropics where hot and humid conditions promote fungal growth. Absorbed aflatoxins are metabolized by the cytochrome P450 enzyme system in the liver into toxic metabolites. Aflatoxin B (AFB)1 is the most toxic, carcinogenic and mutagenic naturally occurring toxin...

The liver is a vascular-rich solid organ. Safe and effective dissection of the vessels and liver parenchyma, and control of intraoperative bleeding are the main concerns when performing liver resection. Several studies have confirmed that intraoperative blood loss and postoperative transfusion are predictors of postoperative morbidity and mortality in liver surgery. Various methods and instruments have been developed during hepatectomy. Stapling devices are crucial for safe and rapid anastomosis. They are used to divide hepatic veins and portal branches, and to transect liver parenchyma in open liver resection...

Within the broad interest of assembling chiral left- and right-handed helices of plasmonic nanoparticles (NPs), we introduce the DNA-guided organization of left- or right-handed plasmonic Au NPs on DNA scaffolds. The method involves the self-assembly of stacked 12 DNA quasi-rings interlinked by 30 staple-strands. By the functionalization of one group of staple units with programmed tether-nucleic acid strands and additional staple elements with long nucleic acid chains, acting as promoter strands, the promoter-guided assembly of barrels modified with 12 left- or right-handed tethers is achieved...

The docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) contents of Pacific saury (Cololabis saira), a fatty fish and staple of the Japanese diet, have been reported to decrease after cooking. This study compared the DHA and EPA contents remaining in saury after grilling, pan-frying or deep-frying to center temperatures of 75, 85, or 95 °C, and examined physical loss, lipid oxidation, and thermal degradation as mechanisms of DHA and EPA loss. Temperature changes inside the saury were monitored using thermocouples, while DHA and EPA contents, oxygen radical absorbance capacity, and measurements of lipid oxidation (that is, carbonyl value and thiobarbituric acid value) were determined chemically...
