    This paper deals with design and general features of shark gillnets operated along Mumbai coast. A PA monofilament of 0.60 to 1.0 mm diameter and selvedge meshes of PE of 1 to 2 mm diameter were used for shark set gillnets along Mumbai coast. Mesh size of the main webbing ranged from 120 to 200 mm with average of 144.4 ± 10.83 mm and rigged with a hanging coefficient of 0.41 to 0.51 with average of 0.42 were commonly used. A hung length ranging from 40 to 105 m with mean of 59 ± 10.37 with total hung depth varying from 6.42 to 10.58 m with average of 8.15 ± 0.49 m. Shark gillnet had a total length of 260 to 456 m with mean of 350.71 ± 28.53 m. The nets were operated mostly at a depth up to 18 m very near to the shore and were of set type of gillnet. Polyamide (PA) monofilament netting of 0.16 to 0.32 mm diameter and of mesh size 26-200 mm were generally used for construction of gillnets throughout the Mumbai coast. Polyamide (PA) monofilament has completely replaced PA multifilament in all the nets except those targeted i.e. white sardine and seerfish

    A study on quantity and value of juvenile fish landings was carried out in the gillnet fishery of three selected landing centers along Mumbai coast viz., Versova, Cuff Parade and Mahim in India using Out board motors (OBM), Inboard motors (IBM) and non-motorised gillnetters respectively. The data on the quantity and value of landed juveniles were collected and analysed to reach a consensus on the gross economic loss on account of juvenile fishing. A bio-economic model was used to estimate economic loss due to juvenile fishing of 18 commercially important species of finfish and shellfish. A huge economic loss was recorded due to fishing of juveniles of 18 species by three different gillnet sectors. The analysis indicated that IBM gillnetters at Cuff Parade incurred maximum loss of Rs. 62.26 crores with major contribution from juveniles of seerfish followed by non-motorised gillnetter (Rs.29.98 crores) at Mahim and 25.33 crores in OBM gillnetters at Versova

    The plants, rituals and spells that 'cured' helminthiasis in Sicily

    <p>Abstract</p> <p>Background</p> <p>The author reports on the plants, rituals and spells used against worms and the so-called <it>scantu </it>(fright) in some areas of Sicily. The work is based on ethnobotanical research carried out, prevalently, between 2002-2006, in some areas of Eastern, South-Eastern, North-Central and South-Central Sicily.</p> <p>Methods</p> <p>This research is based on dialogue. Senior 'healers' were contacted; furthermore, doctors, teachers, farmers and in general 'experts' with herbs and 'magic' rituals. Information was collected about the way the plants of folk medicine are prepared. The interviewees were also invited to recite prayers and spells against helminthiasis.</p> <p>Results</p> <p>The author has highlighted the importance of how, in some parts of Sicily, some ailments like helminthiasis and other correlated pathologies like <it>scantu </it>are 'treated' and, especially within the rural social classes, by folk medicine remedies, herbal practises, particular prayers, rituals and spells.</p> <p>Conclusion</p> <p>As regards health/illness, it should be noted that in the last ten years conventional medicine has provided very satisfactory results even resolving potentially mortal pathologies. However, in certain social classes, there is no real collaboration between conventional and folk medicine; so for some senior citizens, the 'healer' with his rituals and empirical and magical herbs is still the person to turn to for the 'cure' of particular ailments. Interest in these practises from ancestral heritage in an advanced country like Italy, is only relevant if the aim is to recoup a cultural identity which is already in decline.</p> <p>It is significant to report a piece: on 14 October 2007 the news on a well-known national Italian TV channel reported an interview with a 94 year-old man from Arbatax (Sardinia) referred to as a 'healer' because both his townspeople and others from all over the world go to him for his cures. He is not paid except in kind and has been known to cure St. Anthony's fire, burns, scalding and marine fungal infections, by smearing his saliva over the infected part and reciting 'special words'.</p

    Evolution of long-term vaccine-induced and hybrid immunity in healthcare workers after different COVID-19 vaccine regimens

    BACKGROUND: Both infection and vaccination, alone or in combination, generate antibody and T cell responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, the maintenance of such responses-and hence protection from disease-requires careful characterization. In a large prospective study of UK healthcare workers (HCWs) (Protective Immunity from T Cells in Healthcare Workers [PITCH], within the larger SARS-CoV-2 Immunity and Reinfection Evaluation [SIREN] study), we previously observed that prior infection strongly affected subsequent cellular and humoral immunity induced after long and short dosing intervals of BNT162b2 (Pfizer/BioNTech) vaccination. METHODS: Here, we report longer follow-up of 684 HCWs in this cohort over 6-9 months following two doses of BNT162b2 or AZD1222 (Oxford/AstraZeneca) vaccination and up to 6 months following a subsequent mRNA booster vaccination. FINDINGS: We make three observations: first, the dynamics of humoral and cellular responses differ; binding and neutralizing antibodies declined, whereas T and memory B cell responses were maintained after the second vaccine dose. Second, vaccine boosting restored immunoglobulin (Ig) G levels; broadened neutralizing activity against variants of concern, including Omicron BA.1, BA.2, and BA.5; and boosted T cell responses above the 6-month level after dose 2. Third, prior infection maintained its impact driving larger and broader T cell responses compared with never-infected people, a feature maintained until 6 months after the third dose. CONCLUSIONS: Broadly cross-reactive T cell responses are well maintained over time-especially in those with combined vaccine and infection-induced immunity ("hybrid" immunity)-and may contribute to continued protection against severe disease

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immune responses and infection outcomes were evaluated in 2,686 patients with varying immune-suppressive disease states after administration of two Coronavirus Disease 2019 (COVID-19) vaccines. Overall, 255 of 2,204 (12%) patients failed to develop anti-spike antibodies, with an additional 600 of 2,204 (27%) patients generating low levels (&lt;380 AU ml−1). Vaccine failure rates were highest in ANCA-associated vasculitis on rituximab (21/29, 72%), hemodialysis on immunosuppressive therapy (6/30, 20%) and solid organ transplant recipients (20/81, 25% and 141/458, 31%). SARS-CoV-2-specific T cell responses were detected in 513 of 580 (88%) patients, with lower T cell magnitude or proportion in hemodialysis, allogeneic hematopoietic stem cell transplantation and liver transplant recipients (versus healthy controls). Humoral responses against Omicron (BA.1) were reduced, although cross-reactive T cell responses were sustained in all participants for whom these data were available. BNT162b2 was associated with higher antibody but lower cellular responses compared to ChAdOx1 nCoV-19 vaccination. We report 474 SARS-CoV-2 infection episodes, including 48 individuals with hospitalization or death from COVID-19. Decreased magnitude of both the serological and the T cell response was associated with severe COVID-19. Overall, we identified clinical phenotypes that may benefit from targeted COVID-19 therapeutic strategies

    This study aims to determine the effect of sermons in Sunday worship on the maturity of the congregation's faith in the Gereja Kristen Indonesia Setia (GKSI) Merauke. The method used is quantitative. The hypothesis is that there is a positive and significant influence between the sermon in Sunday worship on faith maturity. The population is the GKSI Merauke congregation, amounting to 292 people with a sample of 30 people. The instrument used was a closed questionnaire. Validity is tested using the product-moment correlation formula. Data were analyzed using the correlation technique (rxy), tested for the significant relationship with the formula (t) and the test of determination (r2), and simple regression. The successful test was tested by F, then to find out the effect regression equation was carried out with the formula Y = a + bX. The results showed the effect or r2 = 51% and significant influence or F count = 28.65 where it is known that F table = 4.17 and obtained the meaning of the simple regression equation Y = 7.25 + 0.87X. This study concludes that the sermon on Sunday worship positively and significantly affects the congregation's faith maturity

    Educational institutions have implemented online distance learning and teaching since the COVID-19 pandemic in Indonesia around March 2020. This research was conducted to find the effectiveness and its factors of virtual learning on English speaking skills in the early of pandemic. This study was a descriptive qualitative. This research was conducted at STMIK Sinar Nusantara Surakarta in Central Java. The time of research was started from April until June 2020 and it was conducted for Second-semester students in the academic year of 2019/2020 with 50 students for the number of populations from Information System program. For the research findings, virtual learning was not effective in grammar and fluency aspects and it was less effective in accent and vocabulary aspects for second-semester students of Information System program. Some factors have occurred in those lack of effectiveness, such as, the limitation of time in presenting speaking skill, the inefficiency of lecturer in correcting the students' accent directly, difficulties of students in understanding material, limitations of English students' vocabularies, and tendency of students' speaking presentation based on the textbook
