  • Tumors are surrounded by a variety of tumor microenvironmental cells. Profiling individual cells within the tumor tissues is crucial to characterize the tumor microenvironment and its therapeutic implications. Since single-cell technologies are still not cost-effective, scientists have developed many statistical deconvolution methods to delineate cellular characteristics from bulk transcriptome data. Here, we present an overview of 20 deconvolution techniques, including cutting-edge techniques recently established. We categorized deconvolution techniques by three primary criteria: characteristics of methodology, use of prior knowledge of cell types and outcome of the methods. We highlighted the advantage of the recent deconvolution tools that are based on probabilistic models. Moreover, we illustrated two scenarios of the common application of deconvolution methods to study tumor microenvironments. This comprehensive review will serve as a guideline for the researchers to select the appropriate method for their application of deconvolution.

  • Necrobiosis lipoidica (NL) is a rare, idiopathic, chronic granulomatous inflammatory disease of collagen degeneration with the risk of ulceration. Many procedures have been proposed to treat this rare disease. In this study, we applied LDM®-MED for the management of NL, and this condition in our patient was chronic and refractory to other therapeutic options. To the best of our knowledge, no study has explored treatment of NL using ultrasound. Our results suggest that application of LDM®-MED seems to be an effective treatment option for NL. Long-term and systematic studies are needed to determine whether such application of LDM®-MED will be an innovative and effective treatment option for NL and various kinds of chronic wounds.

  • Viable cells of periodontal ligament would be an important factor for the successful replantation of an avulsed tooth. Therefore, it is critical to choose the storage medium for the preservation of traumatically avulsed teeth. Growth factors and hormones could be considered for the therapeutic application of the maintenance of viable periodontal ligament fibroblasts (PDLFs). Epidermal growth factor (EGF) has been suggested as an important player for the regeneration and wound healing process on other tissues. Therefore, EGF was evaluated for the therapeutic application on avulsed teeth. In addition, the synergic effect of EGF with tri-iodothyronine (T3) and heparin-binding epidermal growth factor-like growth factor (HB-EGF). The cell proliferation of PDLFs was determined by MTT assay and increased dose-dependently up to 10 ng/ml in the presence of EGF. Maximum cellular growth was shown at the concentration of 10 ng/ml EGF. Also, EGF promoted the wound healing of PDLFs examined by in vitro wound healing assay. Combined effects of EGF with T3 or HB-EGF on the proliferation of PDLFs were also studied. Interestingly, EGF showed the synergic effect on the proliferation of PDLFs with T3 and HB-EGF. To find out the mechanism of the synergic effect of EGF and T3, the effect of T3 on the expression of endogenous EGF receptor was determined by RT-PCR. The result was that T3 enhanced the expression of EGF receptor in PDLFs. It suggested that EGF might be a good choice for a therapeutic application, which can be used as combination with T3 and HB-EGF.

  • A novel agglomeration technique, termed "Spherical Crystallization Process", which can transform directly the fine crystals produced in the crystallization or the reaction process into a spherical shape was developed. By this technique, needle like crystals such as salicylic acid were transformed into free flowing and directly compressible agglomerates. Sphericaly agglomerated aminophyline crystals were obtained directly from the reaction system, which could reduce the preparation processes, e. g. synthesis, crystallization and agglomeration, into only one step. Sodium theophyline monohydrate agglomerates were prepared by salting out, the rate process of which was described by a first order kinetics. Agglomerated crystals of ndw complex of indo-methacin-mepirizole were prepare with this technique; an improved therapeutic effect of the resultant crystals was expected. expected.

  • Since utilization of metal is attractive research area applicable to medical applications, several metals have been studied by many scientists. Zr-89 is known as one of important radioisotopes nowadays. Novel ligands for Zr-89 have been developed, and Zr-89-based radiopharmaceuticals have been employed for positron emission tomography (PET) study. In this highlight review, recent advances on Zr-89 utilization for radiophramaceuticals are illustrated.

  • Whole-body positron emission tomography (PET) imaging with 18-F deoxyglucose (FDG) is a molecular imaging modality that detects metabolic alteration in tumor cells. In various human cancers, FDG-PET shows a potential clinical benefit in screening, tumor characterization, staging, therapeutic follow-up and detecting recurrence. In gynecologic cancers, FDG-PET is also known to be effective in characterization of adnexal masses, detection of recurrence, and lymph node invasion. This review discusses the clinical feasibility and future clinical application of this imaging modality in patients with cervical cancer, ovarian cancer, and other gynecologic cancers.

  • Wilms Tumor is a great therapeutic success story within pediatric oncology. Therefore, accurate initial staging is needed to assess tumor spread and to assign patients appropriately to the different risk branches. However, it is recognized that FDG-PET can provide useful information about tumor and has better accuracy than CT and MRI for staging, but its role in Wilms tumor is unclear. According to clinical research data, FDG PET may be useful for the management of selected patients with Wilms tumors.

  • Nonmelanomatous skin cancer includes basal cell carcinoma, squamous cell carcinoma, merkel cell carcinoma and dermatofibrosarcoma protuberance. So far, there have been a few reports that $^{18}F-FDG$ PET was useful in the evaluation of metastasis and therapeutic response in nonmelanomatous skin cancer, however, those are very weak evidences. Therefore, further studies on the usefulness of $^{18}F-FDG$ PET in nonmelanomatous skin cancer are required.
