Sustainable development is a critical concern in this fast-paced technological world. Therefore, it is essential to employ renewable resources to move towards sustainable development goals (SDGs). The polyols attained from renewable resources, including lignin, chitosan, vegetable oils, cellulose, etc. and the polymers derived from them have attracted the attention of the majority of researchers, both in academia and industry. The development of bio-based polymers from vegetable oils start emerging with different properties to generate a value-added system. This review will give an impression to readers about how coatings generated from vegetable oils can find a way towards better protective properties against corrosion either by using fillers or by using molecular structure modifications in the system, thus covering a range of vegetable oil-based self-healing polymers and their application in anti-corrosion coatings.The article covers coating materials using bio-chemical derived molecules (vegetable oils) and their properties including mechanical, self-healing and anti-corrosion properties. 相似文献

The UK’s response to COVID-19 has been widely criticized by scientists and the public. According to EuroMOMO, a European mortality monitoring initiative, the excess mortality that may be attributable to COVID-19 in England is one of the highest in Europe, second only to Spain. While critiqued from a public health perspective, much less attention is given to the implications of the pandemic outbreak for the right to health as defined under international human rights law and ratified by member states. Using the UK as a case study, we examine critically the extent to which the government’s response to COVID-19 complied with the legal framework of the right to health. We review further key states’ obligations on the right to health and assess its suitability in times of pandemic. Finally, we offer some recommendations for an update of the right to health. This paper adds to the body of literature on the right to health and human rights based-approaches to health. 相似文献

We report an extremely rare case of spontaneous complete disappearance of a large chronic subdural hematoma in a 78-year aged man with a significant mass effect and a large midline shift which was diagnosed around 6 weeks before admission. Repeat NCCT of the head in our department to everyone’s surprise revealed almost complete spontaneous resolution. Spontaneous resolution of a large chronic subdural hematoma is extremely rare, and the scarce literature whatsoever is available is especially in cases of immune thrombocytopenic purpura where steroids may play a role in the stabilization of neomembranes. Our interest is in this case because of the benign clinical course despite a large size causing severe mass effect and large midline shift. Chronic subdural hematoma is a common entity in the elderly generally seen weeks following minor trauma. Surgical evacuation of a chronic subdural hematoma remains the gold standard treatment, but controversy exists regarding the best surgical option. Spontaneous resolution of a chronic subdural hematoma has also been reported rarely, but mainly in patients with immune thrombocytopenic purpura. 相似文献

Corneal blindness is the fourth leading cause of blindness worldwide, with 10 million people having bilateral corneal blindness, nearly 80% of all corneal blindness cases are avoidable and are reversible. Corneal transplantation (CT) is the most frequently performed type of transplant across the world. This review was conducted with the objective of identifying if it is safe to harvest the cornea from the patients died due to COVID-19 and preventing the chances of transmission from donor to the recipient or healthcare worker handling the harvested cornea. A total of 45 articles were found with the keywords and out of all, only 16 fulfilled the inclusion criteria. RT-PCR is the technique of choice for detection of virus in the corpse and the sample analyzed was a pharyngeal swab. Available literature states unavailability of sufficient evidence-based studies proving presence of virus in the cornea or tear of COVID affected patients There is no proven consensus on presence of Virus in cornea. It is important to follow preferred practice guidelines so as to restart eye banking and do at least the emergency surgeries without having risk of disease transmission and keeping ourselves safe. 相似文献

Background Context
A paucity of data exists studying outcomes of patients with syringomyelia undergoing spinal deformity correction. The literature does not stratify patients by syrinx size, which is likely a major contributor to outcomes.Purpose
The study aimed to compare differences in outcomes between patients with large (≥4?mm) and small syrinxes (<4?mm) undergoing spinal deformity correction.Design
This is a retrospective review.Patient Sample
The sample included 28 patients (11 with large syrinx [LS, >4?mm] and 17 with small syrinx [SS, <4?mm]).Outcome Measures
The outcome measures were radiographic, operative, and neurophysiological measures.Methods
We retrospectively reviewed 28 patients with syringomyelia who underwent spine deformity surgery with 2-year follow-up. Demographic, surgical, and radiographic data were collected and compared preoperatively and at 2 years.Results
The LS group (11 patients) trended toward more left-sided thoracic curves (36% vs. 18%, p=.38) and was more likely to have had a Chiari decompression (45% vs. 12%, p=.08). The LS patients had larger preoperative major curves (LS=66° vs. SS=57°, p=.05), more thoracic kyphosis (LS=42°, SS=24°, p<.01), and greater rib prominences (LS=16°, SS=13°, p=.04). The LS patients had more levels fused (LS=12.2, SS=11.2, p=.05), higher estimated blood loss (EBL) (LS=1068?cc, SS=832?cc, p=.04), and a trend toward less percent correction of the major curve (LS=57%, SS=65%, p=.18). Four of 11 LS patients (36%) did not have somatosensory evoked potentials, and one of these also did not have motor evoked potentials. Neuromonitoring changes occurred in 3 of 11 (27%) LS patients and in none of the SS patients, with no postoperative deficits.Conclusions
Outcomes of patients with syringomyelia undergoing spine deformity surgery are dependent on the size of the syrinx. Those with large syringomyelia are fused longer with more EBL and less correction. Spine surgeons should be aware that these patients are more likely to have less reliable neuromonitoring, with a higher chance of experiencing a change. 相似文献150.

BackgroundWeightlifting is a power and dynamic strength game. Performance of weightlifters during competition depends on absolute and relative power output achieved by them. To enhance power and strength in weightlifters, training programmes have frequent high-intensity exercise sessions. On an informal interaction with the sportspersons, they often complain of problems after intense training. There was a felt need to analyse the problems they perceive after intense training.MethodA feedback form was developed after brainstorming with coaches and sports medicine physicians of a sports institute. Thirty-six male weightlifters aged 19.78 ± 4.71 yrs (mean ± standard deviation) of an institute participated after obtaining informed consent. The feedback form was collected and analysed.ResultAfter an intense exercise, participants reported complaints such as increased fatigue (n = 27), sleep problems (n = 26), restlessness (n = 18) and decreased appetite (n = 12). Of the sleep problems, 69.4% (n = 25 out of 36) noticed worsening of sleep, 50% (n = 18) noticed sleep was light after intense training, 58.3% (n = 21) felt difficulty in falling asleep, 47.2% (n = 7) complained of frequent waking up during sleep at night and 77.8% (n = 28) felt sleepy after waking up.ConclusionIntense training encounters certain problems such as fatigue, sleep disturbances, restlessness and decreased appetite. 相似文献
