Hematogones were initially described as mysterious cells in bone marrow smears more than 70 years ago. These cells are normal bone marrow B-lymphocyte precursors with properties that overlap those of lymphoblasts. Their morphological and immunological features are described here with an update on the knowledge of hematogones in hematological and non-hematological disorders.

Laser-based surface processing is an established way for the maskless generation of surface structures and functionalities on a large variety of materials. Laser-driven periodic surface texturing and structuring of thin films is reported for metallic-, semiconductive-, and polymeric films. Here, we introduce subwavelength surface patterning of metal-organic thin films of [Mo2S4(S2CNnBu2)2], a MoS2 precursor. Accurate control of one- and two-dimensional (1D and 2D) periodic patterns is achieved on silicon wafers with a pulsed 532 nm ns laser. With suitable combinations of laser polarization, laser pulse energy, the thickness of the SiO2 passivation layer, and the MoS2 precursor's thin film thickness, high-quality 1D and 2D self-organized periodic structures are obtained in virtually unlimited areas. The material redistribution related to the pattern formation is thermally driven at low laser energies. Increasing pulse energies beyond a threshold level, in our experiments a factor of 2, fully converts the precursor to MoS2.
3. Protamine 2 precursors and processing

Protamine 2 (P2) is synthesised as a precursor protein (pre-P2) which by proteolysis is processed to generate the mature components of the protamine 2 family of proteins (HP2, HP3 and HP4). In infertile patients, abnormal processing of the protamine 2 precursors has been suggested by the detection of an increased presence of precursor forms. However, the presence of small detectable amounts of precursor proteins has been demonstrated also in normal sperm samples, although the variation of pre-P2 in individual human sperm cells had not yet been explored. In the present manuscript we perform a mini-review describing what is known about protamine 2 precursors and P2 processing. In addition, we by immunofluorescence demonstrate the existence of a marked variation in the presence and abundance of pre-P2 in individual sperm cells.
