Combined Drying Technologies for Preserving the Quality of Backyard Averroha Carambola L. in Veracruz, Mexico

/0 Comments/in /by

Star fruit (Averrhoa carambola L.) is cultivated in Asian and Latin American countries and has high nutritional value due to its content of bioactive compounds, polyphenols, vitamins A and C, minerals, and antioxidant activity. However, its high water content makes it highly perishable, limiting its preservation and commercialization; therefore, it is necessary to develop technological alternatives that extend its shelf life without affecting its organoleptic and nutritional quality. The objective of this study was to evaluate combined power ultrasound-assisted drying technologies for obtaining star fruit flakes as a preservation alternative, analyzing their effect on physicochemical, functional, and sensory attributes. Fruit from the Postgraduate College, Veracruz Campus, was used, and osmotic dehydration (OD) curves were performed at 50 and 60 °Brix, using ultrasound (US) as a pretreatment to convective drying (CS). Drying kinetics were performed at 50 and 60 °C, and total phenolic compounds, antioxidant activity (DPPH and ABTS), oxalic acid, color (ΔE), moisture, total solids, water activity (aw), and texture in the center and periphery were evaluated, in addition to sensory analysis. The DO treatments assisted with ultrasound reached equilibrium in less time. The 60°Brix-CUS-60 °C treatment showed lower final moisture content, while the 60°Brix-CUS-50 °C treatment reached an aw of approximately 0.47, favoring microbiological stability. The 60 °Brix DO treatment with ultrasound and 60 °C surface drying showed lower moisture content and higher total solids content. The 60 °Brix DO treatment without ultrasound and 50 °C surface drying preserved phenols better, reducing oxalic acid by >50% and showing improvements in antioxidant activity. High sensory acceptability was obtained. It is concluded that the DO-US-SC combination is effective in preserving carambola with adequate quality and acceptance.

The Effect of Advanced Laser and Interferential Therapy on the Patient of Pes Anserine Bursitis in Occupational Rehabilitation- A Case Report

/in /by

A 30-Year-old male came to hospital with primary complaint of medial side right knee pain. Patient is watchmen by profession and involve long time standing without rest. He was diagnosed for pes anserine bursitis which is inflammatory condition. The aim of the present study is to implement advanced physiotherapeutic intervention with the conventional method for the better and long-term therapeutic effect in point of occupational rehabilitation. The study result concluded that interferential therapy with advanced laser therapy gave significantly swift and long-term effect followed by strength and conditioning of the lower limb. Procedure- a treatment session of 2 weeks included application of IFT and laser at lesion site to facilitate the response of pain and tenderness. We have used the pain scale, which is a visual analogue scale, to assess the efficacy of the modality. For 15 minutes, the patient received laser and IFT treatment. Conclusion- combining IFT and laser therapy can be used to treat pes anserine bursitis.

The Current State of Epidemiological Aspects and Medical and Social Significance of the Problem of Cholelithiasis and its Complications

/in /by

In terms of prevalence, frequency of surgical intervention and economic losses, cholelithiasis belongs to one of the most costly areas of world health care and occupies one of the leading positions in the structure of morbidity. Many authors have proven the leading risk factors for cholelithiasis. However, to this day, there are often difficulties in the timely differential diagnosis of cholelithiasis and breast syndrome. The use of modern highly sensitive research methods does not exclude diagnostic errors that occur in 10–42% of cases.

To date, to help surgeons, further study of this problem is required, because they are aimed at improving the results of surgical treatment of this group of patients.

MRI-Guided Focused Ultrasound, an Emerging Minimally Invasive Technique in Neurology

/in /by

MRI-guided Low Intensity Focused Ultrasound has a wide range of applications in neurological disorders and is superior to other minimally invasive neuromodulation techniques in terms of a better spatial resolution and stimulating deeper brain structures. Parkinson’s disease, Alzheimer’s disease, essential tremor, brain malignancy, epilepsy, nerve block, medication delivery, and stroke are among the neurological disorders which benefit from MRI-guided Low-Intensity Focused Ultrasound. In addition, the safety profile of this minimally invasive neurostimulation technique is also well studied and approved. Therefore, the clinical application of Focused Ultrasound in neurologic disorders should be the focus of future clinical trials.
