A method for diagnosing and monitoring the patient’s general condition has been developed, including the use of the specially developed and registered for clinical use of the device OKO Capillaroscope for non-invasive, non-contact video recording under a large increase in blood flow in the human bulbar conjunctival microvessels using special software that allows: measuring movement speed erythrocytes in individual arterioles, venules, and in the main preferred channels; to fix in microvessels the possible presence of sludge syndrome, stasis of the erythrocyte movement; to assess the number and shape of capillaries, the presence of arteriolar-venular anastomoses, the identity of blood flow in the microvessels of the conjunctiva in the right and left eye; measure arteriole diameters and venules. The method is aimed at a clinical study of the parameters of the microcirculation of the conjunctiva at rest, which allows extrapolating the recorded parameters of the intravascular (rheological) part of the microcirculation system to the state of the microhemodynamics of the whole organism, which reflects the state of general homeostasis. The method can be applied to control and monitor the general condition of a person or patient in any research in experimental, sports or therapeutic purposes, since the determined digital parameters of microcirculation allow to assess the general condition of a person, the response to physical exertion and evaluate the completeness and completeness of therapeutic treatment in various pathologies due to somatic or local degenerative changes in the patient’s body.

The investigation of the vascular microcirculation system is important for diagnosis, assessment of the severity and nature of pathological processes in human body, monitoring the effectiveness of treatment. Monitoring the state of microcirculation in impaired respiratory function of the nose helps to study the subtle mechanisms of regulation of vascular−tissue relations. To do this, there were used the biomicroscopic methods to study capillary blood flow, one of the most relevant and promising is optical capillaroscopy of the nail bed. This method makes it possible to identify at the evidence level the peculiarities of the functioning of the peripheral circulatory system by the state of the capillary system and to evaluate the effectiveness of treatment by the rheological properties of blood in hematological practice. There were examined 145 patients by means of computer capillaroscopy to study the rate of capillary circulation in the patients with pathology of intranasal structures and nasal breathing disorders. All patients underwent a complete clinical examination, routine instrumental examinations, and computer capillaroscopy using a video capillaroscope with a visual magnification of up to 550 times. The obtained images were stored and processed according to a special software. During the characterization of the capillaroscopic picture there were evaluated: pathological tortuosity, change in the caliber of arterioles and venules, disorganization of the capillary network, the number of functioning capillaries. Changes in the speed and nature of capillary blood flow (accelerated, slow, stasis) were observed. The optical capillaroscopy method allows not only to visually assess the condition of microvessels, but also to determine such an important parameter as blood circulation, actually, it can replace the study of laser Doppler. Such data will be important in the diagnosis of respiratory and olfactory disorders and the formation of adequate tactics for their treatment. Key words: microcirculation, microcirculatory tract, capillary circulation, nasal obstruction, nasal breathing disorders, pathology of intranasal structures, computer capillaroscopy.

New developments in instrumentation and data analysis have further improved the perspectives of hyperspectral imaging in clinical use. Thus, hyperspectral imaging can be considered as “Next Generation Imaging” for future clinical research. As a contactless, non-invasive method with short process times of just a few seconds, it quantifies predefined substance classes. Results of hyperspectral imaging may support the detection of carcinomas and the classification of different tissue structures as well as the assessment of tissue blood flow. Taken together, this method combines the principle of spectroscopy with imaging using conventional visual cameras. Compared to other optical imaging methods, hyperspectral imaging also analyses deeper layers of tissue.

Abstract Non-invasive estimation of bladder volume could help patients with impaired bladder volume sensation to determine the right moment for catheterisation. Continuous, non-invasive impedance measurement is a promising technology in this scenario, although influences of body posture and unknown urine conductivity limit wide clinical use today. We studied impedance changes related to bladder volume by simulation, in-vitro and in-vivo measurements with pigs. In this work, we present a method to reduce the influence of urine conductivity to cystovolumetry and bring bioimpedance cystovolumetry closer to a clinical application.

The article, based on an analysis of judicial and investigative practices, highlighted the complex issues relating to the legal status of an expert and a specialist, ensuring their independence, evaluating and using the conclusions of an expert and a specialist by the court in strict compliance with and ensuring the principle of equality of the parties in the criminal process. The defense has the right to request the cross-examination of the expert, regardless of whether he was questioned at the pre-trial investigation stage. This does not exclude the possibility of using the previous testimony in court (protocol, audio, video recording), but only for the purpose of establishing contradictions. Refusal to satisfy the petition is a violation of the Convention requirements for a fair trial and equality of the parties. A tacit refusal of any guarantee of justice is not excluded, but at the same time, the existence of such a refusal must be proved «unequivocally». The court is obliged to accept as evidence from the defense the findings of the expert on the same issues on which the prosecution provided the findings of the state examination. The rules of admissibility of evidence may sometimes be contrary to the principles of equality of the procedural capacities of the parties and the adversarial process or otherwise affect the fairness of the proceedings. The rules for the admissibility of the conclusions of a specialist should not deprive the party of defense of the opportunity to effectively challenge them, in particular, by using them in the case or obtaining other opinions and conclusions. The state prosecution is obliged to disclose to the defense all available evidence (the conclusions of the examination for the benefit of the prosecution, and for the benefit of the defense). Hiding expert conclusions is a violation of the principle of equality of the parties. In the context of globalization, it is often necessary to use evidence obtained in the territory of a foreign state. All documents must be provided to the defense for review in plain language. If at the end of the investigation some documents are not translated and it is provided only after the start of the judicial review, the court is obliged to announce their contents and provide them for review. According to the Court, this does not constitute a violation of the right to defense. In case of poor-quality translation, the party has the right to request a re-transfer. If documents in a foreign language remain in the case file (without translation), this does not indicate a violation of convention standards if the arguments contained in these documents are not based on the indictment or conviction. Thus, in order to provide methodological assistance to law enforcement agencies and courts in the application of legislation related to the involvement of experts and the assessment of their findings, it is necessary to develop guidelines with regard to international standards, convention requirements, as well as to make changes and additions to existing legislation. Key words: criminal proceedings, «scientific judges», questioning of an expert, expert opinion, specialist opinion, European Court of Human Rights.

In 260 patients with cerebral circulatory insufficiency of different expressiveness the state of linear cerebral blood stream was determined by method of cerebral radiocirculography. For integral evaluation of the state of cerebral blood supply effectiveness ratio of linear blood flow in blood supply was calculated. Complete parallelism between clinical manifestations of cerebral artherosclerosis and expressiveness of disorders of cerebral blood flow has not been revealed. In patients with discirculatory encephalopathy of stage I blood flow by cerebral vessels is lowered when reducing cerebral blood supply. Blood flow is prevailing in the left hemisphere. In patients with discirculatory encephalopathy of stage II in cerebral blood supply retrograde venous support is revealed, allowing to maintain vascular blood supply at a relatively high level. Intersemispheric hemodynamic differences are being smoothed. Discirculatory encephalopathy of stage III is characterized by sharp worsening of cerebral hemodynamics. Supply level in the left cerebral hemisphere appears to be at a lower level, than in the right one. During further pathology development hemodynamic disorders achieve a critical level, beyond which vascular catastophe or death occurs.

In the discipline of Islamic law research, strong proofing and clear Istinbat method are key pillars in the construction of Islamic law based on the application of the science of usul al-fiqh and maqasid al-shari'ah. However, what happens at the state of Johor’s fatwa institution is the opposite. The fatwa research methods applied by the Fatwa Committee of Johor in resolving current fatwa issues is not based on the right and true discipline of Islamic law research. In fact, current inputs related to fatwa issues are not explicitly stated in the method of determining the law either in the form of reality or scientifically verified. Therefore, this paper will discuss the fatwa procedures undertaken by the Fatwa Committee of Johor based on the methods applied in resolving current issues. The research methodology adopted is library and interview methods. This study shows that fatwa management and production in the state of Johor is placed under the jurisdiction of the Mufti of Johor’s Department. The methods adopted by the Fatwa Committee of Johor covers two methods, namely: internal research methods including literature review through the application of original source and proofs based on syarak. Second: field research method that includes an external review or going to the location of study such as conducting observation, questionnaires and interviews including referrals to specialists of different fields. Maslahah and mafsdah consideration are also implemented by the Fatwa Committee in every fatwa decision based on the standard that meets the interests of maqasid al-shari'ah. Keywords: Metode, fatwa, istinbat, usul al-fiqh, maqasid al-shari’ah ABSTRAK Dalam disiplin penyelidikan hukum Islam, kekuatan pendalilan dan kaedah istinbat yang jelas merupakan tunggak utama dalam pembinaan hukum Islam berasaskan kepada aplikasi ilmu usul al-fiqh dan maqasid al-shari’ah. Namun begitu, apa yang berlaku di institusi fatwa negeri Johor adalah sebaliknya. Kaedah penyelidikan fatwa yang diaplikasi oleh Jawatankuasa Fatwa Negeri Johor dalam menyelesaikan isu fatwa semasa tidak berasaskan kepada disiplin penyelidikan hukum Islam yang tepat dan sebenar. Malahan input-input semasa yang berkaitan dengan isu fatwa juga tidak dinyatakan secara jelas dalam kaedah penentuan hukum sama ada dalam bentuk realiti yang berlaku atau pembuktian secara saintifik. Justeru, kertas kerja ini akan membincangkan prosedur fatwa Jawatankuasa Fatwa Negeri Johor berdasarkan metode-metode yang diaplikasi dalam menyelesaikan isu-isu yang bersifat semasa. Metodologi kajian yang digunakan dalam kajian ini adalah melalui metode perpustakaan dan metode lapangan. Hasil kajian menunjukkan bahawa pengurusan dan pengeluaran fatwa di negeri Johor hanya terletak di bawah bidang kuasa Jabatan Mufti Johor. Metode fatwa yang diamalkan oleh Jawatankuasa Fatwa Negeri Johor merangkumi dua metode iaitu pertama, kaedah penyelidikan dalaman yang merangkumi kajian kepustakaan menerusi pengaplikasian dari sumber asas dan dalil-dalil syarak. Kedua, kaedah penyelidikan lapangan yang meliputi kajian luaran atau turun ke lokasi kajian seperti observasi, soal selidik dan temubual dan rujukan kepada pakar dalam bidang yang berlainan. Pertimbangan maslahah dan mafsdah juga dimplementasikan oleh Jawatankuasa Fatwa dalam setiap keputusan fatwanya berasaskan standard yang menepati kepentingan maqasid al-shari’ah. Kata kunci: Metode, fatwa, istinbat, usul al-fiqh, maqasid al-shari’ah
