PROBLEM: Gene expression studies require appropriate normalization methods for proper evaluation of reference genes. To date, not many studies have been reported on the identification of suitable reference genes in buffaloes. The present study was undertaken to determine the panel of suitable reference genes in heat-stressed buffalo mammary epithelial cells (MECs). Briefly, MEC culture from buffalo mammary gland was exposed to 42 ∘ C for one hour and subsequently allowed to recover at 37 ∘ C for different time intervals (from 30 m to 48 h). Three different algorithms, geNorm, NormFinder, and BestKeeper softwares, were used to evaluate the stability of 16 potential reference genes from different functional classes. Our data identified RPL4, EEF1A1, and RPS23 genes to be the most appropriate reference genes that could be utilized for normalization of qPCR data in heat-stressed buffalo MECs.

SOLUTION: Identification of Appropriate Reference Genes for qRT-PCR Analysis of Heat-Stressed Mammary Epithelial Cells in Riverine Buffaloes (Bubalus bubalis)

PROBLEM: We live in a hostile environment, surrounded by microbial pathogens and subject to a range of physical and chemical insults. To survive in this environment, vertebrates have evolved complex immune systems. A key element of this defence is the deployment of rapid response elements at the most probable sites of attack, which are the epithelial-cell boundaries between the body and the environment in the skin, gut and lungs. As the body's largest and most exposed interface with the environment, the skin has a central role in host defence. Before the relatively recent discovery of the immunological defences of skin, the cutaneous interface was viewed as a passive barrier between the host and the hostile environment. In the past few decades, however, it has become apparent that the mechanical aspects of epidermal defence are reinforced by a versatile and robust system of immune surveillance 1 (FIG. 1) . The crucial role of immune surveillance in maintaining homeostasis is evident from the marked increase in the frequency and severity of cutaneous malignancies and infections when immune function is limited, for example in patients with genetic and acquired immunodeficiency disorders and in those receiving immunosuppressive therapy after organ transplantation 2,3 . The regulation of skin defence mechanisms is also crucial, as inappropriate or misdirected immune activity is implicated in the pathogenesis of a large variety of acquired inflammatory skin disorders, including psoriasis, atopic and allergic contact dermatitis, lichen planus, alopecia areata and vitiligo 4-10 . The role of immune dysfunction in these conditions is emphasized by their response to immunosuppressive therapeutic interventions [11] [12] [13] [14] . Understanding the mechanisms of immune surveillance in the skin and tissue-specific immune responses also has important implications for the rational design of vaccines. To promote protective immunity, an immunization protocol must elicit not only an antigenspecific immune response, but also an effective memory response that will provide long-lived protection at the most probable sites of invasion. This applies equally to immunization against infectious organisms, which in most cases invade through the skin or the epithelia of the gastrointestinal or respiratory systems, and to the elicitation of immune responses against tumours. As we discuss, the route and means of adjuvant stimulation that is used can affect the effectiveness and utility of specific vaccine strategies. In this review, we discuss these issues in the context of recent advances in our understanding of cutaneous immune mechanisms, highlighting the interaction of The skin, as the primary interface between the body and the environment, provides the first line of defence against a broad array of microbial pathogens and trauma. In addition to its properties as a physical barrier, the skin has many active defence mechanisms. In this review, we discuss the interaction between the innate and adaptive immune systems in the skin as a model for immune function at epithelial-cell interfaces with the environment. How these mechanisms account for the robust nature of cutaneous immune surveillance and how their dysregulation drives the pathogenesis of inflammatory skin disorders and skin-based tumours are the subjects of this review.

SOLUTION: IMMUNE SURVEILLANCE IN THE SKIN: MECHANISMS AND CLINICAL CONSEQUENCES

PROBLEM: The introduction of the Individual Visit Scheme (IVS), which allows Mainland Chinese travelers (hereafter called Chinese travelers) to visit Hong Kong on an individual basis, has been beneficial to the fast recovery of the local economy in Hong Kong from severe acute respiratory syndrome (SARS). The IVS travelers, together with the packaged travelers who visited Hong Kong by joining packaged tours, are presently forming the largest segment of inbound travelers to Hong Kong. Despite the significant economic contributions of Chinese travelers to Hong Kong in general, and to the foodservice sector in particular, there has been an absence of prior studies on IVS travelers' behavior of selecting restaurants in the existing hospitality and tourism literature. This paper reports on an exploratory study that investigated the perceived importance of attributes that pertain to the selection of restaurants from the perspective of IVS and packaged travelers from Mainland China. Empirical findings of a questionnaire survey with 230 Chinese travelers, including 127 IVS travelers and 103 packaged travelers, showed that the respondents in general viewed the included attributes as relatively important. In addition, only two attributes exhibited significant differences between IVS and packaged travelers. Findings of this research would be useful for hospitality and tourism practitioners to better prepare for receiving the growing number of Chinese travelers. r

SOLUTION:
