Branching morphogenesis, the creation of branched structures in the body, is a key feature of animal and plant development. It requires the coordinated interplay of multiple types of epithelial cells with the surrounding extracellular matrix. Cell migration, proliferation, and extracellular matrix dynamics have different roles in driving budding in different organs. This historical review article summarizes the first founding literature data concerning branching morphogenesis occurring in kidney, lung, vascular system, mammary glands and neurons.

In-depth studies have identified many hormones important for controlling mammary growth and maintaining lactation. One of these is melatonin, which is synthesized and secreted by the pineal gland to regulate circadian rhythms, improve antioxidant capacity, and enhance immunity. Prolactin is secreted by the pituitary gland and is associated with the growth and development of mammary glands as well as initiation and maintenance of lactation. The hypothalamus-pituitary system, the most important endocrine system in the body, regulates prolactin secretion mainly through dopamine released from tuberoinfundibular dopaminergic neurons. This review provides a reference for further study and describes the regulation of lactation and prolactin secretion by melatonin, primarily via the protection and stimulation of tuberoinfundibular dopaminergic neurons.

Osseointegration can be defined as a direct connection, both structural and functional, between living bone and the surface of an artificial implant. Indeed, the word comes from the Greek term for 'bone' and 'to make whole'. In dentistry, once dental implants are placed, the body will react with osseointegration, enabling the implants to become a permanent part of the jaw. There are many benefits to this type of implant, compared with traditional tooth replacement options, not least that dental implants mimic the strength and functionality of a natural tooth. Dr Shuhei Tsuchiya is a researcher based in the Division of Oral and Maxillofacial Surgery at Nagoya University, Japan, who is interested in a range of areas, including regenerative medicine and the extracellular matrix. One of his key preoccupations, though, is shedding light on osseointegration. He and his team are working to unravel the mysteries of the mechanism.

Phylum Cnidaria is an ancient venomous group defined by the presence of cnidae, specialised organelles that serve as venom delivery systems. The distribution of cnidae across the body plan is linked to regionalisation of venom production, with tissue-specific venom composition observed in multiple actiniarian species. In this study, we assess whether morphological variants of tentacles are associated with distinct toxin expression profiles and investigate the functional significance of specialised tentacular structures. Using five sea anemone species, we analysed differential expression of toxin-like transcripts and found that expression levels differ significantly across tentacular structures when substantial morphological variation is present. Therefore, the differential expression of toxin genes is associated with morphological variation of tentacular structures in a tissue-specific manner. Furthermore, the unique toxin profile of spherical tentacular structures in families Aliciidae and Thalassianthidae indicate that vesicles and nematospheres may function to protect branched structures that host a large number of photosynthetic symbionts. Thus, hosting zooxanthellae may account for the tentacle-specific toxin expression profiles observed in the current study. Overall, specialised tentacular structures serve unique ecological roles and, in order to fulfil their functions, they possess distinct venom cocktails.

<b><i>Introduction:</i></b> Although Mustafa Kemal Atatürk (1881–1938) was a national hero with his intrepid and enlightened attempts to establish modern Turkey from the remnants of Ottoman heritage, he had been suffering from lifelong “kidney disease” that appeared with intermittent flank pain and fever without an identified source. However, we think that this physical pain that he endured only increased his motivation to focus on his military and political aims. <b><i>Methods &amp; Results:</i></b> In this historical review article, we have focused on his personal medical life and specifically his “kidneys” from the beginning of the complaint till his death through European medical and political history with geographic locations and speculated upon it via past, near past, and recent medical literature. <b><i>Conclusion:</i></b> Mustafa Kemal Atatürk, the great military and political leader for his country, had always suffered from uro/nephrological problems throughout his life. We think that this was one of the reasons that urology has been privileged and thus to be the oldest separated medical surgical branch in Turkey and to some significant extent with European urological history.

Biological tissues are not uniquely composed of cells. A substantial part of their volume is extracellular space, which is primarily filled by an intricate network of macromolecules constituting the extracellular matrix (ECM). The ECM serves as the scaffolding for tissues and organs throughout the body, playing an essential role in their structural and functional integrity. Understanding the intimate interaction between the cells and their structural microenvironment is central to our understanding of the factors driving the formation of normal versus remodelled tissue, including the processes involved in chronic fibrotic diseases. The visualization of the ECM is a key factor to track such changes successfully. This review is focused on presenting several optical imaging microscopy modalities used to characterize different ECM components. In this review, we describe and provide examples of applications of a vast gamut of microscopy techniques, such as widefield fluorescence, total internal reflection fluorescence, laser scanning confocal microscopy, multipoint/slit confocal microscopy, two-photon excited fluorescence (TPEF), second and third harmonic generation (SHG, THG), coherent anti-Stokes Raman scattering (CARS), fluorescence lifetime imaging microscopy (FLIM), structured illumination microscopy (SIM), stimulated emission depletion microscopy (STED), ground-state depletion microscopy (GSD), and photoactivated localization microscopy (PALM/fPALM), as well as their main advantages, limitations.

Ayurveda is one of the most ancient medical science in the world. Ayurveda is known as the science of life. It is not only medical science, but it is also a way of life. In Ayurvedic literature many Aacharyas (Sage) like Atreya Punarvashu,Dhanvantari,Sushruta,Charaka,Vagbhata and other commentators of samhitas (Ancient iterature) have made, its importance the knowledge of Sharir (body) to have undoubtedly for the sake of knowledge. In Ayurveda, Rachana sharir is a very important part of this science to make a person a good physician or a good surgeon. In Rachana Sharir, Marma sharir is very important topic. By knowing this, a person may become a good physician or surgeon. Marma sharir and its practical application are very important during surgery and to understand the injury at marma site, their prognosis and possible prevention is necessary. Inside the body, there is a specific anatomical location which is called a vital point. Keywords: Mamsa (muscle), marma (vital part), jivsthan (life site), Parinam (result), pariman (dimension)
