The effects of acute administration of Chinese aphrodisiacs sold in Blantyre City on sperm characteristics and fertility profile in guinea pigs

Background Chinese aphrodisiacs have become popular remedy for sexual dysfunction and improvement of libido in men in Malawi. However, selling of these drugs seems not to be well regulated. Probably the aphrodisiacs that are currently on the market have unknown efficacy, potency and safety profiles. The aim of this study was to assess the efficacy of imported Chinese aphrodisiacs using guinea pigs as a model. Materials and Methods Two types of drugs were purchased from vendors in Blantyre City. Tonic tea, which was purported to improve erectile function and libido, and sperm multiplier tablets which were claimed to increase the sperm count. The tonic tea was prepared by soaking one tea bag in 100ml boiling water. The tea was cooled and administered to eight male experimental animals in varying doses. Each animal was introduced into a separate cage with a female guinea pig. Sexual behaviour such as mounting, sniffing behind the female were observed and recorded. Each sperm multiplier tablet was dissolved in distilled water and administered to the experimental animals in the morning and evening for seven days. At the end of the treatment, the experimental and control animals were sacrificed, their semen collected and analysed sperm motility, concentration and morphology. Results For the tonic tea, there were no statistical differences between the experimental and the control animals in terms of the number of mountings and sniffing behind the female. The sperm multiplier drug showed statistically significant differences between the experimental and the control animals in terms of the sperm motility (78.24 ± 1.35 vs. 86.54 ± 1.88, p< 0.05), and concentration (54.28 ± 1.24 vs. 67.59 ± 2.12, p<0.05). Conclusion The tonic tea did not show any efficacy in improving erection and libido. The sperm multiplier tablets, purported to increase sperm production, significantly increased the sperm motility, sperm concentration in the treated animals.

El Señorío de Chillón. De Bernardo de Cabrera a Sancho de Alburquerque

El presente artículo se refiere a la evolución que experimentó la villa de Chillón en los decenios centrales del siglo XIV. Chillón, perteneciente al término de Córdoba, fue señorío de relevantes personajes de la época. Entre 1344 y 1350, perteneció a Bernardo de Cabrera, privado de Pedro IV de Aragón. Posteriormente, pasó a poder de Juan Alfonso de Alburquerque, que desempeñó la misma función en la Corte del rey Pedro de Castilla. Reintegrada posteriormente a la jurisdicción de Córdoba, fue entregada por Enrique II a su hermano don Sancho, que no logró vencer la oposición de la ciudad y no llegó realmente a posesionarse de la villa, la cual terminó por vender a Diego Fernández de Córdoba, alguacil mayor de Córdoba, en 1370.

Traditional part-time grazing: a more sustainable sheep milk and cheese production in the Basque Country

[EN] The concept of sustainability when referring to food production rests, in general, on 3 main aspects: 1) respect for the environment; 2) economic and social benefits for all involved in production; and 3) production of sufficient quantity of quality food at an accessible price. In this contribution we focus on the main aspects of the traditional sheep's milk and cheese production (under the Denomination of Origin Idiazabal Cheese) in the Basque Country that contribute primarily to its sustainability. It is based on the local latxa or carranzana breeds of sheep, adapted to the mountainous terrain. The sheepherder takes advantage of local resources to reduce management costs by combining indoor dry forage and concentrates with outdoor grazing throughout lactation, according to local pasture availability, and thus avoiding having to buy large amounts of feed. This system facilitates recycling of manure, fertilising pastures and forest at the same time. Use of local breeds helps maintain biodiversity of sheep breeds. Cheese is produced industrially (44.5% of the total cheese produced in 2008) from milk of many flocks, or artisanally (38.3%) by the sheepherders with the milk from their own flocks. Transforming their own milk into cheese is advantageous for the following reasons: 1) higher economic returns as compared to selling the milk to cheese factories because cheese price directly sold to consumers is more competitive than industrial cheese sold in supermarkets; 2) increases the value of women's work (over 80% of the cheese makers are women) in the community and their self-esteem; 3) it creates rural jobs and contributes to rural development; 4) we have demonstrated both with experimental and commercial flocks that part-time grazing allows the sheepherder to obtain high yields of milk, and cheese, of high nutritional and functional quality. Currently a less sustainable, intensive sheep's milk production with foreign, imported breeds kept indoors constantly is gaining favour among milk producers because of its perceived higher economic profitability.

ECONOMIC ANALYSIS of AMAZON RIVER PRAWN FARMING TO THE MARKETS FOR LIVE BAIT and JUVENILES IN PANTANAL, BRAZIL

The implementation of a hypothetical aquaculture facility with hatchery, nursery and grow-out earthen ponds for raising the Amazon River Prawn Macrobrachium amazonicum in the Pantanal was considered. Eight larviculture cycles per year were projected: four to produce post-larvae for stocking in grow-out bait ponds, and four to stock nursery tanks to sell juveniles as seed to grow-out farms, which produce prawns for human consumption. Annual production would be 146,880 dozen bait prawns and 2,938 thousand juveniles. The assumed sale prices were US$ 1.38 per dozen baits and US$ 15.39 per thousand juveniles. The net present value was US$ 555,890.79, internal rate of return was 48% per year, payback period was 2.4 years and benefit-cost ratio was 3.90. The breakeven price to cover total costs per dozen baits was US$ 0.70 and per thousand juveniles was US$ 17.00, indicating that the selling price assumed for juveniles in base scenario is not realistic. Net return was US$ 84,773.80. The results indicate that this activity would be a lucrative and attractive investment in the Pantanal.

Private security beyond private military and security companies:exploring diversity within private-public collaborations and its consequences for security governance

The aim of this special issue is to widen the existing debates on security privatization by looking at how and why an increasing number of private actors beyond private military and/or security companies (PMSCs) have come to perform various security related functions. While PMSCs produce security for profit, most other private sector actors make profit by selling goods and services that were originally not connected with security in the traditional understanding of the term. However, due to the continuous introduction of new legal and technical regulations by public authorities, many non- security related private businesses nowadays have to perform at least some security functions. Little research, however, has been done thus far, both in terms of security practices of non- security related private businesses and their impact on security governance. This introduction explains how this special issue contributes to closing this glaring gap by 1) extending the conceptual and theoretical arguments in the existing body of literature; and 2) offering a range of original case studies on the specific roles of non- security related private companies of all sizes, areas of businesses, and geographic origin.

Consecuencias literarias del 11-S: la representación de la violencia en la novela angloamericana

In my eight years as a professional journalist, I have been a front line observer of the extreme level of violence which occurs everyday in our society. As victims, consumers or perpetrators of violence, this phenomenon is now a part of our existence. As a reporter for the Spanish national newspaper El País I have been witness to the most terrible acts of violence. In Venezuela, with one of the highest rates of criminality in the world, I saw piles of bodies stacked up in mortuaries. In Argentina, I reported on the most brutal crimes including the rape of children by policemen. I believe that my interest in the manifestations and causes of violence was aroused during my time as a journalist. On a personal level, I was deeply affected by the twin poles of attraction/repulsion which the violent images produced in me. The first time I visited New York in 2003, I talked to various people who were selling photos of the victims of the Twin Tower attacks. They had laid out their wares along the wire fence that separated Ground Zero from the main public areas. One particular photograph made an indelible impression on my mind: a ghost like corpse covered in white dust which was streaked with blood. It is an image I will never forget. If I remember well, a complete album of these gruesome images cost about ten dollars. At the same time, I also became interested in islamic terrorism: its complexity and the great impact it has made on Western society. One only has to look at the front page of the press around the world to read about war, terrorism or the constant violation of human rights. The words Al-Qaeda, Daesh, Boko Haram and Islamic State have sadly become parts of our everyday language. The nihilistic philosophy which promisess eternal life in exchange for self-inmolation is a new, highly worrying reality, especially painful when it involves young people who become indoctrinated through the social media. They have become the most loyal supporters of a fanatical and uncompromising version of Islam. The stark reality is that these young recruits to Jihad (holy war) were born in places like London, Paris, Rome or Madrid...
