'We need to share our stories': the lives of Pakistanis with intellectual disability and their guardians.

INTRODUCTION: The experiences of Pakistanis with intellectual disabilities (IDs) and their family members have been underexplored empirically. METHOD: The present study sought to address this gap by understanding the lives of five Special Olympics Pakistan athletes and their guardians through PhotoVoice. FINDINGS: Through thematic analysis, we present the primary theme concerning Pakistan's cultural context that provides an empirical exploration of cultural beliefs about intellectual disability, cultural expectations and support received by people with intellectual disabilities and their guardians. DISCUSSION: We discuss implications for research and practice.

Morphology of the testis of the one-humped camel in relation to reproductive activity.

Histological and morphometric studies on the camel testis have been carried out systematically at regular monthly intervals during a period of one year. The testicular weight was minimal during summer, while the maximum weight was attained during the coldest months from November until March. Diameters of the seminiferous tubules were multiphasic with a tendency to be wider during summer. The ratio of the area occupied by seminiferous tubules to that occupied by interstitial tissue revealed that the latter occupied a larger area than that of the seminiferous tubules during winter, while a reversed relationship occurred from March onwards and was especially marked after April, i.e. in summer. In addition, spermatogenesis was noted in all testes examined throughout the year; however, there was a difference in the quality and quantity of spermatogenic cells between the monthly groups evaluated. November, December and January were the months in which spermatogenic activity was most striking. A correlation was established between testicular weight, amount and quality of testicular interstitial tissue, spermatogenesis and epididymal sperm content and, hence, testicular function on the one hand and season of the year on the other hand. The cyclic structural changes in the testis appeared to be in parallel with the rutting activity of the camel. It was suggested also that the camel is not a typical seasonal breeder as it does not go through sexual quiescence. The reproductive activity of the camel builds up during September and October, and the animal is in actual rut during November, December, January and February, with a drop in March and thereafter.

Studies on the poll glands of the one-humped camel in relation to reproductive activity. I. Seasonal morphological and histochemical changes.

The poll glands of the camel have been studied histologically and histochemically. An active gland, as observed between September and March, with a peak period in November and December, consists of sharply demarcated lobules separated by thin strands of connective tissue. Alveoli and proximal parts of excretory ducts are either lined with flat/simple cuboidal epithelium or with tall cells possessing distal protruding tips almost occluding the lumina; both segments, i.e. alveolus and proximal part of excretory duct, are therefore secretory. In the inactive gland there is an apparent increase in the interlobular stroma with massive deposition of collagenous fibres. The alveoli are lined with squamous to low columnar epithelium. The structural appearance in the castrate animal is essentially the same as that of the inactive gland except for its remarkable amount of interlobular tissue. Both delta 5-3 beta- and 17 beta-hydroxysteroid dehydrogenases have been demonstrated histochemically in the secretory portions of the gland. Their activity is restricted to the period between September and March and is comparatively highest during November and December. It is concluded that the morphological, enzymatic and secretory activities of the poll gland are correlated with testicular activity and rutting behaviour. It is suggested that the poll glands could be a source of sex pheromones.
